The beauty of the Stanley Cup playoffs is that we're seeing the best of the best battle it out to see who can win it all.

The irony of the NHL postseason, though, is that no matter how good these teams are, they've still got some issues to contend with as best as they can along the way.

We're going to take a look at each of the teams in the postseason and highlight the biggest issue they've got to contend with if they're going to skate around the ice with the Cup in June.

A few teams have made it more than apparent what might keep them from advancing while others are better at keeping it under wraps. Don't worry, we're pretty good sleuths around here and can work out each of their Achilles' heels.

Join us as we cruise around the playoffs and show you what those teams would rather hide deep within the earth to never be seen again.

New York Rangers

Overconfidence

Sure, the Rangers have a 2-0 series lead on the Washington Capitals and that's got them out to a great start, but something that stood out in Game 2 was an aura of overconfidence. That wasn't there in Game 1 when they were able to build a lead and completely shut down Washington.

If New York is going to play the part of being the NHL's best team, it's going to need that stone-cold attitude that portrays a demeanor that screams, "We're better than you, we know it, and we're going to continue showing you why."

To the Capitals' credit, they pushed a lot harder in Game 2 and gave the Rangers a lot more to chew on heading to D.C. for Games 3 and 4, but New York is the top team in the postseason for a reason, which means they should be able to handle Washington with some ease.

The Rangers have been able to keep Alex Ovechkin quiet and that's necessary, but as long as they take the Caps' fierce response in Game 2 as a warning that the road to the Stanley Cup will not be easy, they'll handle the playoffs a lot better and with a lot more focus.

Washington Capitals

Depth

The Capitals knew their road to the Stanley Cup was going to be a lot tougher than just about everyone else who wasn't named the New York Islanders.

Washington has gotten Herculean goaltending from Charlie Lindgren all season while their offense figured itself out. Alex Ovechkin's blazing second half showed he can still be a force to be reckoned with which also allowed support stars like Dylan Strome, Tom Wilson and John Carlson to reap the benefits.

But when tasked with dealing with a deep team like the New York Rangers, the stress those matchups has put on younger players like Connor McMichael and Martin Fehervary is difficult to manage.

Those players are good, but over the course of a playoff series, dealing with the likes of Artemi Panarin, Mika Zibanejad, Chris Kreider and Adam Fox along with trying to get more pucks past Igor Shesterkin, is asking a lot.

Asking all of them to do it to win four games against the Rangers makes it out to be an almost insurmountable task. The series isn't over, of course, but being down 2-0 makes it imperative to hold serve on home ice to survive.

Florida Panthers

Penalties

By now, we know the Panthers play a rough and tumble game that can draw the ire of even the humblest of opponents.

It's even easier to do against a heated and hated rival like Tampa Bay. And those kinds of kerfuffles are OK because it generally means no one is coming out of it with a power play.

The problem the Panthers ran into in Game 2, though, was committing other infractions that were hard to ignore. Whether it was cross-checks, running into Lightning goalie Andrei Vasilevskiy or getting careless with the stick otherwise, these issues put Tampa Bay on the power play which meant Florida tempted fate all game.

The Panthers held the Lightning to one power-play goal in six chances, and although that's a ratio that comes away looking like a victory, the fact that they gave Tampa Bay six chances to score with the extra man is no good.

While the Lightning also had a power-play goal in Game 1, it came with 10 seconds to play in the game and only made the final score closer than it really was.

Game 2 needed Carter Verhaeghe's customary overtime heroics to give Florida a 2-0 series lead. If they take penalties the way they did in Game 2 the rest of the way, the Panthers will be primed to be upset.

Tampa Bay Lightning

Offensive Juice

It's weird to look at the Lightning and think that of any of the possibilities for what might ail them down 2-0 to the Panthers, offense could be one of them.

And yet, despite losing each of the first games by 3-2 scores, it's the overall lack of offensive fire power at 5-on-5 that's hurting them. Through the first two games, Tampa Bay has 82 total shot attempts, 62 of them unblocked, and 29 shots on goal at 5-on-5 (via Natural Stat Trick).

Even though the Panthers are blocking shots and Sergei Bobrovsky has been tough to figure out, the Lightning have to get more pucks on the net.

Even though Bobrovsky is a world-class goaltender, he's not without his flaws on occasion, and Tampa Bay must put more pressure on him if it's going to start turning the tide in Game 3 and beyond.

Relying on getting more power-play opportunities to generate goals is a fool's gambit in the postseason, but the Lightning know full well that to win in the playoffs, they have to score at even strength. To do that, they must get more shots actually on goal.

Carolina Hurricanes

Staying Focused

Carolina has showed in the first two games against the Islanders that it's the better team and that's why it's got a 2-0 series lead. Sort of.

What's worrisome, though, is that it took a complete lack of composure and maturity with a lead by New York to cost itself Game 2.

The Islanders blowing a 3-0 lead in that game because they decided to sit on the lead and allow Carolina to feast upon the opportunity to put a barrage of shots toward Semyon Varlamov virtually unimpeded (apart from blocking shots anyway) showed a lot about the Hurricanes.

Yes, they were able to take full advantage of the Islanders and pull off a stunning comeback late in the game, but Carolina shouldn't have been in that position in the first place to then need to do that. The Hurricanes didn't look anything remotely like the dominating team they showed they can be.

While the Islanders can make life difficult for any team, the number of shot attempts the Hurricanes have generated along with the possession time they've maintained, the first two games shouldn't have been as difficult as they were.

If the 'Canes want to go deep, they'll need to sharpen their focus quickly.

New York Islanders

Immaturity

When we say the lack of maturity is the Islanders' biggest flaw, we're not necessarily talking about the meltdown they had after blowing a 3-0 lead on the way to losing Game 2 5-3 and falling into a 2-0 hole in the series.

That's part of it, but it's not the whole story. It's more about how once they got up 3-0, they opted to hunker down and tried to gum up the ice and dump the puck to whittle away time and get a win before Carolina found a way back into the game.

That, of course, failed and instead of heading back to Long Island with a 1-1 split, they came up smaller than small and now have to hold serve at home to make it a series.

The Islanders are loaded with veteran players and watching them trying to hold it down for 30 minutes and allow a Carolina team that's made its name over the years by throwing everything toward the net at all times was quixotic in nature and tragic in its outcome.

The Isles can beat the Hurricanes, but they've got to stay out of their own way to do it.

Boston Bruins

Patience

The Bruins easily could be up 2-0 on the Toronto Maple Leafs. They've got the stars, the depth and talent, but the way they dropped Game 2 showed an uncharacteristic lack of defensive control.

Boston is often known for being a steady, patient team on defense that can change the game by using its defensive ability to slow down opponents, create turnovers and transition rapidly from defense to offense.

Instead, Game 2 highlighted a lack of control at times that allowed the Maple Leafs the chance to take any momentum the Bruins thought they gained right back and even things up.

That lack of patience in the third period allowed Auston Matthews to get a step on the Bruins back line and all the space and time he could want to deke Linus Ullmark for what proved to be the game-winning goal.

Sticking to details will allow the Bruins to go deep in the playoffs, but the occasional fits where they lose their focus will be their undoing if they don't correct it.

Toronto Maple Leafs

Tact

There's no questioning the amount of elite talent the Maple Leafs have. The kind of brilliance they have should be enough to push them deep into the playoffs.

But as we've gotten to know over the years, it's not that easy for them and often it's the decisions that come from behind the bench that hurt them as much as the ones on the ice.

The Bruins took full advantage of Toronto trying feebly to set a tone in Game 1 by attempting to beat Boston with the kinds of tricks and nonsense its opponents are known for.

The problem there was the Bruins are also good at not taking the bait when it's so obviously being used to cause problems out of nowhere. The Leafs handed the Bruins countless power plays which they cashed in on and rolled to an easy win.

Game 2 showed that their talent can win games and sticking to what they're good at can be enough to beat even the other great teams in the league. If that's the lesson they took from the first two games, then maybe Toronto can make it easier on itself rather than creating its own scenarios for heartbreak.

Dallas Stars

Penalty Kill

Picking out a flaw based on one game is both easy and risky. For the Dallas Stars, it's hard to look at anything apart form their penalty kill as a big issue.

Dallas' PK went 0-for-2 against Vegas in Game 1 and considering it lost 4-3, that's a big problem. The Stars had one of the better penalty-killing units during the regular season as they had the eighth best group in the NH. It's probably a one-game blip, but what if it's not?

We could have gone with goaltending as their biggest problem considering Jake Oettinger made 11 saves on 15 shots, but one tough game isn't reason enough to be hugely concerned.

Of course, the 25-year-old didn't have as strong of a season as he had a year ago, so that's reason to be a little nervous. But having to deal with a near-fully healthy Vegas team looking to repeat isn't anyone's idea of fun.

Vegas Golden Knights

The Offense? Maybe Goaltending?

We know the kind of firepower Vegas has. With Mark Stone back to join Jack Eichel, Jonathan Marchessault, William Karlsson and Tomas Hertl, it's a wicked hitlist of talent for the Golden Knights to fill the net.

Of course, the Golden Knights put up only 15 shots on goal in Game 1 and still came away with the win. Scoring twice on the power play went a long way to helping that out, but posting just 13 shots at 5-on-5 isn't going to win too many more games.

We're pretty sure Vegas' offense will be fine, but seeing the Dallas defense able to get in its way so well is concerning.

Goaltending was an area of concern heading into the playoffs given the fuzzy health status for both Logan Thompson and Adin Hill, but the former played well enough to win Game 1.

A couple of the goals he allowed were a bit worrisome, but one game is a very small sample size.

Winnipeg Jets

Handling attack speed

We're not about to question the talents Jets goalie Connor Hellebuyck. He's probably winning the Vezina Trophy this year and for good reason.

But after such a lights-out regular season, having to deal with the Colorado Avalanche attack for a playoff series would be enough to make any goalie look bad. Fortunately for the Jets, they were able to outscore the Avs in Game 1, but things changed in Game 2.

The way the Avs play with their high-speed and quick puck movements can cause headaches and they have for the Jets. Hellebuyck has allowed 10 goals in two games, and they head to Denver for Games 3 and 4 knotted up at 1-1 in the series.

Winnipeg has to find a way to gum up the Colorado offense and make it difficult for them to make such quick plays that force Hellebuyck to move laterally and create more openings for shooters.

Colorado Avalanche

Goaltending

Hats off to Colorado goalie Alexandar Georgiev for changing the story in Game 2 after an abysmal performance in Game 1. He allowed seven goals on 23 shots and despite the Avalanche scoring six times, they weren't able to pull out a win.

It was such a poor performance it made us wonder why Colorado management didn't have a more experienced backup when Pavel Francouz was unable to play and ultimately retired.

But in Game 2, Georgiev looked like the goalie we watched last season in stopping 28 of 30 shots to spur Colorado to a Game 2 win.

If the guy we saw on Tuesday night is the one we'll see all the time, we like the Avs' chances. If not, the hot stove for goaltending this offseason will be scorching in Denver.

Vancouver Canucks

Health

The series between Vancouver and Nashville was set to be a tight one given how hot the Predators were to close out the season, but the Canucks have been outstanding all year and were riding high going into the playoffs.

Their stirring comeback in Game 1 seemed to highlight what's made them so good this year, but it came at a cost.

Starting goalie Thatcher Demko was injured and is out week-to-week with Casey DeSmith in charge in the meantime. Game 2 proved to be frustrating and not just because of Demko's absence but defenseman Tyler Myers' as well.

Those absences loosened up the Canucks just enough to allow the Preds to take Game 2 despite them hunkering down for the entire third period to preserve the win. Vancouver outattempted Nashville 60-30 over the final two periods and 84-36 for the full game, but it was a 4-1 win for the Predators nonetheless.

If Vancouver plays like that the rest of the way, it will do fine, but without Demko holding down the net, a series that was going to be difficult in the first place gets a lot dicier for the Canucks.

Nashville Predators

Defensive wherewithal

The Nashville Predators have been able to score some goals in the first two games of the series against Vancouver, which alleviated one question going into the matchup. What has to be a concern, though, is the overall defense of the group.

The Predators are allowing so many shot attempts already. At 5-on-5 through two games, the Canucks have 111 shot attempts to their 62. That means Vancouver is getting nearly 65 percent of all shot attempts at 5-on-5 and that's not great for the Preds defense.

Add in that Vancouver has over 63 percent of the expected goals, and it starts to look more miraculous that Nashville is headed home with the series tied.

Clearly, Juuse Saros has been strong for the Preds, but they're tasking him with a lot more work against one of the best teams in the league.

Anything can happen in a seven-game series, but there's no way coach Andrew Brunette will like seeing things this skewed.

Edmonton Oilers

Even Strength

The display of offense the Edmonton Oilers had in Game 1 was a lot of fun to watch.

Seeing Zach Hyman put up a hat trick and Connor McDavid record five assists was a special night. Of course, the final score was 7-4, and although it looks close it wasn't really indicative of how it went.

Still, the Oilers scored three times on the power play and being even with a team that you skated circles around for most of it at even strength would be a bit annoying if I were in coach Kris Knoblauch's shoes.

Sure, score effects and such, but still. The Oilers aren't a team that can ease up on anything ever. They have to go deep into the playoffs at long last. They have to make it to a Stanley Cup Final lest they waste another brilliant year from McDavid and Leon Draisaitl.

The only question is whether the Kings can provide them with the proper kind of test to see if they are ready to make that jump.

Los Angeles Kings

Speed

Perhaps one of the more troubling things for the Kings after watching Game 1 was seeing how easily the Oilers were able to rip past them on the ice and use their speed to create opportunities off the rush.

It's almost impossible to keep pace with McDavid, but it wasn't just him the Kings had trouble keeping up with. By now, we know L.A. likes to play big and do things the way it has for the past 10-plus years.

That means playing big, strong physical hockey, and while the Oilers don't shy away from that themselves, they can also more easily skate away from trouble to create opportunities up the ice.

The Kings frustrated everyone during the season for how effective they've been at deploying the 1-3-1 forecheck that reminds everyone a little too much of the bad old days when watching hockey was painful.

But the Kings are going to have to be a lot better at it and far more disciplined to take down the Oilers. Giving Edmonton a ton of power plays didn't work well for them a year ago and after giving up three power-play goals in Game 1, it's off to a bad start already.
