Its an even deal to be, The Dallas Mavericks get back Kidd, but loose on expiring contracts, young players, and good help out players. But the Mavericks got the better of the deal. They will be the team to beat in the west with a triple double machine, and a high power offensive contributor.
Nets on the other hand got the best deal they could get out of any other trades they had earlier. They got a young developing pg from the west now playing in the east, and they got a big man Diop (expiring contract) that will help out. PLus there first round pick from last year will be getting more playing time (Marcus Williams )
Both teams got good deals out of it.
