Should have been Henderson for Bias.
Maxwell for Walton helped bring a title.
Rondo and Perk were both acquired during draft trades. Fultz for Tatum + Langford (who was traded to get White). That Nets trade was the gift that kept on giving. If they hadn't traded the 2018 pick for Kyrie, they would have been in position to get SGA.
White trade is definitely up there.
I think these kind of evaluations have gotten harder in recent years, because movement of contracts has become as much a part of trades of veterans as movement of players and picks.
Nominally speaking, the Celtics traded Marcus Smart, Danilo Gallinari, Mike Muscala and Julian Phillips (who) for Kristaps Porzingis, Marcus Sasser (also who), and a first round draft pick. Smart for KP
and a pick makes no sense, unless you consider that Kristaps, if not traded, was going to opt out and hit UFA, leaving Washington with nothing. The decision to bring KP here was a brilliant one, but as a trade it can't really be evaluated alongside the McHale/Parish deal or the Robey for DJ deal.
The Celtics also traded the fossilize remains of Kemba Walker, a 1st round pick, and a second round pick to OKC for Al Horford, Moses Brown, and a second. This is a great deal because they shed salary while adding a very good player.
The White deal wasn't about contract so much, unless SA was doing it in part to shed salary - but even if so it was a miscalculation.
