Times like these, I'm really very thankful that our GM and owner are not completely incompetent.
The worst mistake Ainge has made in his stint as GM that Celtics fans would probably unanimously agree upon is probably Fab Melo.
Every move Ainge has made, otherwise, has kind of made sense. Even Jermaine O'Neal, who I personally don't like very much at all, seemed like a very good idea at the time (4 centers! We're talking about Kendrick Perkins and ex-All Star Jermaine O'Neal coming off the bench) and the damage done by JO was pretty much contained.
Hell, even the Fab Melo pick doesn't seem too bad in retrospect. PJIII and Moultrie haven't panned out much, yet. Looking back, it was a gamble worth taking.
It hurts to know we missed out on all of Ezeli, Jeffrey Taylor, Dreymond Green...hell even Quincy Acy and Khris Middleton look like they'll be more capable basketball players than Melo.
But, man, Knicks fans have it far far worse with their cap space ruined, their future ruined, basically stuck in purgatory. Top that off, JR Smith, Felton and Woodson are making Knicks fans really hate their team.
