Perk is what he is... and we'd still be a .500 team with him. We were very good with Shaq last year, and even JO and Semih played better than him (because of his injury) while he was in green last year.
I miss Perk? yeah, but I miss TA even more, and it was a bigger mistake to let him go for an extra year. Krstic + Green (without the heart condition) were clearly the better package. Things have gone very bad for the Celtics, but without the Perk trade they'd be basically the same. Rondo's smile? He'd better mature, because he's a top 3 PG who could end being a top 10 because of his lack of focus.
I wish Perk all the best, but I don't think he'll end his current contract with the Zombies. But if the Celtics don't win, I hope he gets a ring.
