The final day of the NHL combine in Buffalo, New York, tested the athleticism, strength and stamina of many of the top prospects who are vying to get selected high in the 2016 NHL draft. 

While several big names such as Patrik Laine, Jesse Puljujarvi, Matthew Tkachuk and Olli Juolevi opted against taking part in drills Saturday, presumptive No. 1 overall pick Auston Matthews went full bore, and likely top-five pick Jakob Chychrun turned some heads as well.

In addition to a closer look at how Matthews and Chychrun performed, here is a rundown of notable measurements and drill results. More comprehensive numbers are available at the NHL Central Scouting website.

Breaking Down Top Prospects

Auston Matthews

After being one of the top scorers in the Swiss league this past season and Team USA's best player at the World Championships, Matthews entered the combine as a virtual lock to go No. 1 overall to the Toronto Maple Leafs.

Even so, the Arizona native decided to take part in a full allotment of drills, acquitting himself well across the board.

Here is a look at how Matthews performed, courtesy of the Toronto Star's Kevin McGran:

The NHL's official Twitter account provided a Vine of Matthews' performance in the agility test:

Craig Custance of ESPN The Magazine captured some video of Matthews working his way through the pull-up drill:

He also tweeted a video of Matthews pushing himself on the arduous Wingate cycle:

Media swarmed Matthews following his day of testing, and as seen in this video courtesy of the Edmonton Oilers, the talented American was happy with his showing and the fact that he got to measure himself against many of the draft's other top prospects:

Matthews seemingly had little to gain and a lot to lose since he was already entrenched as the top pick, but that didn't stop him from competing, much like Connor McDavid and Jack Eichel did last year.

All eyes were on Matthews with so many other big names not participating in the drills, and he showed why he is considered the consensus No. 1 player.

Matthews already has NHL-caliber size, strength and agility, and all the pieces are in place for him to be a star from day one.

Jakob Chychrun

With Laine sitting out lower-body drills after injuring his knee Friday and other top prospects also not taking part in drills Saturday, Chychrun had an opportunity to solidify his status as the top defenseman in the draft and a deserving high pick.

The Sarnia Sting blueliner ranked inside the top 10 in mean power output, peak power output and the vertical jump.

His showing especially impressed NHL.com's Mike Morreale:

As seen in this photo from the Toronto Maple Leafs' Twitter account, Chychrun showed off his considerable athleticism and leg strength during the force plate test:

When interviewed following the combine, Chychrun displayed a positive attitude and seemed pleased with his overall performance, according to the Winnipeg Jets on Twitter:

Most mock drafts have Matthews, Laine and Puljujarvi coming off the board in the first three picks, but things appear to be open beyond that.

Chychrun, Juolevi and Mikhail Sergachev are all in the running to be the top defenseman in the draft, and Chychrun may have put himself in the driver's seat in that debate at the combine.

The Florida native also has a strong body of work after posting 49 points in 62 OHL games this past season, and he proved to the NHL teams that were keeping tabs on him Saturday that he has the physical ability to match his on-ice production.
