The Golden State Warriors know what it takes to win at the NBA's highest level.

And after failing to escape the Play-In Tournament, they also know they don't have enough to make that happen.

"We know clearly what this team was. It wasn't good enough," Warriors general manager Mike Dunleavy Jr. told reporters. "There's no doubt about that, there's no what-ifs."

Marginal changes aren't getting this group into the championship chase, either. This should be the summer of big swings in the Bay Area, as the Warriors have the assets needed to broker a blockbuster and the need to put more high-end talent around franchise centerpiece Stephen Curry.

Kevin Durant, Phoenix Suns

Dismiss the notion of Kevin Durant rejoining the Dubs at your own peril. The 35-year-old swingman could be on the hunt for a scenery change after the Suns' first-round sweep, and the Warriors have quite the opportunity to make a recruiting pitch with Curry, Durant and coach Steve Kerr all joining forces again at the Olympics.

"Durant and Curry will reunite in July as members of Team USA. Kerr is the head coach," NBC Sports Bay Area's Monte Poole noted. "Assuming no movement in the interim, they will have almost six weeks to engage in conversation and reminiscence. ... A KD-Warriors reunion is not as far-fetched as it might seem."

During Durant's three seasons in Golden State, the Warriors had a .740 winning percentage, booked three Finals trips and claimed a pair of league titles. Durant, a hand-in-glove fit with this offense, was Finals MVP during each of those championships.

He has since struggled to make the superteam setup work in Brooklyn and Phoenix, where he "never felt comfortable with his role" this past season, per The Athletic's Shams Charania and Doug Haller. Finding the right role for Durant in Golden State would be simple. It'd be the same one he so magically filled just a few seasons back.

Brandon Ingram, New Orleans Pelicans

Brandon Ingram should, in theory, probably be untouchable. He is a 26-year-old star coming off one of the most efficient campaigns of his career, and he fills up a stat sheet like few others. He has averaged at least 20 points, 4.5 assists and 4.5 rebounds in each of the past four seasons; only eight other players can claim the same, per StatHead Basketball.

Having said all that, Ingram isn't exactly the model of great health. After playing 79 games in his rookie season of 2016-17, he hasn't reached the 70-game mark since. He has never become the defensive player his physical tools say he should be, and he just played a mostly disastrous series in New Orleans' first-round sweep.

There's at least a chance the Pelicans make him available this summer. And, flaws and all, he is someone the Warriors should go after.

He isn't quite as prolific of a perimeter shooter as you'd want from a Curry co-star, but Ingram's ability to create for himself and his teammates would still be hugely helpful. Plus, there might be another level of offensive efficiency he can reach if Curry's gravity and Golden State's system help bring out his best.

Lauri Markkanen, Utah Jazz

Are we pushing the boundaries of realism by including Lauri Markkanen here? Perhaps. The Jazz could absolutely align their future to his with a massive contract extension this offseason.

But will this team—a lottery participant during each of his first two seasons in Salt Lake City—be good enough quickly enough to capitalize on the soon-to-be 27-year-old's prime? The fact that question isn't easily answered in the affirmative is the reason it feels somewhat safe to speculate on his future.

If nothing else, Golden State isn't out anything by making a phone call. And with a formidable package built around draft picks (perhaps two firsts and up to four swaps) and young players (Jonathan Kuminga, Brandin Podziesmki, Trayce Jackson-Davis and Moses Moody) to offer, the Warriors have enough to at least get a dialogue going.

And if that dialogue turns into a deal, Golden State would suddenly have its co-star for Curry. Markkanen's per-game averages since joining the Jazz include 24.5 points, 8.4 rebounds and 3.1 three-pointers to go along with his near-spotless 49/39.5/88.5 shooting slash.
