What's silly is people continuing to act like Danny Ainge can do no wrong - when the evidence is quite clear in the other direction.
The man had a great summer 2007. He has done nothing since game 6 of the Finals to help this club repeat. A versatile wing is an absolute necessity if you intend to pinch pennies with Posey. Instead, we get Tony Allen. Strike one - compounded by the fact that the injury prone Mr. Allen has now checked out for the regular season, creating a situation where we have no veteran whatsoever behind Pierce. Godspeed, Billy Walker. Another strike.
PJ retires. No one's fault. But it's again an absolute necessity to get a competent backup 5. Instead, we get O'Blount. Strike two.
Plus, we've not settled on a backup PG, thanks to Pruitt's erratic play.
Danny did an atrocious job last summer, so much so that this team's playoff future is severely handicapped. He's in a performance business, and some of you need to get it through your heads that last year is over. He's not dumb enough to throw the season under the bus for 2013, like some of you are trying to convince yourselves, but he's clearly been unable to adequately equip this team for a serious Finals run.
There are no free passes for one good year, and no doctrine of Ainge Infallability, either. This season's going to end early without significant help.
His performance isn't over. He still has 2 roster spots that he is looking to fill and we'll see what we get. He didn't have a great offseason, but he didn't have an awful one either.
As you said, PJ decided to retire so there's nothing we can do about that. The other center options were either out of our price range (Kurt Thomas) or not good (Elson). DA took a chance that a guy who had loads of talent would put it together in O'Bryant, but that didn't work. But that's not a failure because he got rid of O'Bryant and might sign a better big man then there were available during the offseason in Mikki Moore (or even better Joe Smith). If we get Mikki Moore or Joe Smith, that's a good job of replacing PJ figuring what was available.
In regards to Posey, he was overpaid by the Hornets and they are paying the price for it by having to unload Chandler before it was rescinded. TA was a solid signing for the money. He is injured, but injuries happen. It doesn't have to do with his knee...it's a freak thumb injury. Pietrus and James Jones (2 other options) have also been injured for much of the year.
For the backup pg, we brought back Cassell and he ended up being too old. BTW, chances are the same might have happened to PJ if we had decided to bring him back. DA decided to give Pruitt an opportunity to succeed like he gave Rondo last year. Pruitt has had some good moments, but overall hasn't succeeded IMO. But there's a good chance that we get a Marbury or some other veteran pg.
Lets not judge Ainge's roster moves before it's over. Last year he added PJ and Cassell after the trade deadline. Lets see who he adds this year and what they contribute to our team. And don't forget that PJ was horrible during the regular season, the Hawks series and only started to really contribute in the middle of the Cleveland series. People are romaticicing the contributions of Posey and especially PJ too much. If PJ doesn't hit that huge jumper in game 7, I don't think the opinion of him would be nearly as high.
