I don't recall any team giving up anything of significance at the deadline.
There wasn't a lot, but:
Clippers gave up some draft pick compensation for expiring Marcus Morris.
Miami traded away Winslow for a 36-year-old Iguodala for a playoff run. He will be 37 next season.
Bird rights have their value nevertheless. LaC will try to bring back Morris for example.
True. The Clippers will only have Non-Bird Rights for Morris (since he went to the Knicks as a FA), but since he's not gonna be looking for more than $18 million (120% of his current salary), it works out to the same thing
The Iggy deal looks much worse
Remember the Heat shed about $30 million of deadweight salary
next year, not including Winslow, as well. Given how much the salary cap and luxury tax could contract, it might have saved them quite a tax bill next summer.
Also, Winslow literally didn’t play a minute for Memphis this year, and who knows if we’ll even have a full season next year. I’m not sure that deal worked for either team, but it’s not hard to envision a world where it actually comes out worse for Memphis.
