TP para Edgar

The OP was thinking about Danny as a GM, though...
Perk wasn't going to resign in Boston for the money OKC gave him, so Danny took a gamble. Green+Nenad or whatever Perk and Nate were going to give the team in the Playoffs? I don't think the results would be different if Wade was injuring Rondo anyway. IMO, not a mistake.
Doc would never promise a starting spot or 6th man minutes to TA, so he tried somewhere else and at the end of the season it paid out well for him. Not a mistake.
I don't know if I really miss Eddie House. I'd rather have Nate, who isn't missed here althought he really tried to help the Celtics playing hard D. Maybe I even miss Eddie's kid more than his father. No mistakes here IMO.
Posey wanted multi-year full MLE money. He hasn't done anything since he signed with NO. Not a mistake.
Giving Blount all that money was ugly, a big mistake. Trading for Raef, big mistake. Trading him and #7 for Ratliff and Telfair... well, he still managed to draft Rondo, so it doesn't seem like a disaster, but I remember the Celtic Nation asking for DA's head because of letting Roy and Foye slip away. Roy (health aside) is better than Telfair, and we don't know if there was another way to swap Raef for Ratliff (who didn't play, so the insurance paid his salary) whithout giving up the pick. We'll never know, so I don't think this is as bad as getting Raef and Blount.
Trading Ricky for Wally? that was ugly. I just checked the basketball-reference
page for the 2005-2006 Celtics transactions... ugly trades, specially the one with Minnesota. I think the only good thing that season was making Phoenix draft Rondo for the Celts. And, of course, giving Scals a multi-year contract

The weakest area in Ainge's work is, except for Rondo, evaluating PGs. Marcus Banks, Will Bynum, Orien Greene, Sebas Telfair and Gabe Pruitt... hopefully Bradley and Moore end up being undersized SGs or great combo guards, and not joining that list.
Draft mistakes... drafting Gabe instead of Marc Gasol, but who would have thought he'll end being that good. Drafting Giddens over anyone else hurts also, but we could be the Blazers and it would be terrible.
DA is doing fine... hopefully he can get something out of BBD and sign a Kwame Brown or a better center, and everything must be forgiven. Peace.
