Danny Ainge is a very good talent evaluator. He drafted Al Jefferson mid/late first round, he got Rondo in a trade after the Suns drafted him 21st, he got Big Baby in the second round, he got Leon Powe, who was very solid until he hurt his knee in the second, he ripped off the T-Wolves for KG, he knows what he is doing.

As for some of the misinformation on this thread, Perkins current knee injury is not to the knee he injured last year, it is the other knee, Ainge likes Perkins and knows his value, he wasnt going to be able to pay him and they are basically holding Shaq out for the playoffs, he could play now if he was needed to, he might play a little bit the rest of the regular season but they want to pace themselves and Green allows Ray and Paul to play less minutes the rest of the reg.season.

The one person who will really hate this trade and it might effect him quite negatively is Rondo because Perk is his best friend, they are very close and Rondo is very emotional.
