How do you know a bunch of teams wanted an expiring Korver?
Because reputable reporters quite literally just said tonight that several contenders were interested in Korver, but the Cavs' offer of a first-rounder pushed them over the top?
I'm arguing that contrary to what you seem to think, Atlanta is not going to get much for Millsap. It certainly won't be a bidding war. How many of those has the NBA had at the trade deadline in recent years?
Goran Dragic (Miami, the Knicks, the Lakers, Indiana, Sacramento) and Reggie Jackson (Detroit, the Nets, Indiana) in 2015, to name just two.
The idea that there won't be a bidding war for a good player is ridiculous. That is not how the NBA works; good talent is *always* desirable and teams will pay for it. Not only are teams looking to improve, but trading for Millsap now gives them the inside track on re-signing him if they so choose in the offseason.
No GM is dumb enough to give up significant assets for a 5 month rental who's not going to put them in a position to win a title. The Hawks might get a project or an end of first round pick for him - that's about it.
So the Hawks got a late first rounder for Kyle Korver and I'm expected to buy that they "might" get the same return for a considerably better and more desirable player? Nope. I will gladly revisit this if and when the Hawks trade him.
That said, firstly, the fact that in 2015, Portland's GM traded Will Barton - same guy who was making waves for Sixth Man of the Year/Most Improved Player last year - and a first rounder for Arron Afflalo, who left at the end of the season, already disproves this theory. Clearly, some GM was "dumb enough" to trade significant assets for a rental when he felt it improved his team in the immediate term.
(Oh, and by the way - the Afflalo trade was the result of another bidding war, although on a much smaller scale; Sacramento most notably expressed interest in trading for him at the time).
Secondly, not every single team's goal is to win a championship immediately. Believe it or not, some markets simply want to see competitive teams. The Nuggets have awful fan support due to being a Broncos/Avalanche city and that problem has been compounded with the Nuggets having been bad since 2013. Simply making the playoffs would be a huge improvement for the team, especially if they parlay that into consistent playoff appearances for the near future.
Thirdly, teams like the Nuggets can acquire a guy like Paul Millsap without having to risk their whole future; they have enough assets and players saved up over their last few years of rebuilding.
Millsap doesn't move the needle this season for anyone - save for maybe Toronto.
This is laughably wrong. Millsap immediately improves the fortune of several teams, including OKC, Sacramento, New Orleans, Toronto, Denver, and so on. He turns fringe playoff teams into playoff locks (Sacramento, Denver) and adds a new dimension to the appropriate playoff locks (Toronto, OKC).
