I think the first "hitch" is that PP will want out if KG retires. I , for one, think that KG will retire unless the celtics make the FINALS AND he feels good in the off season.
Pierce will be getting a huge check from the celtics, I know the man likes to win but the celtics will be winning enough and the $$$ will be huge. There is just as much chance as the celtics trade/release him.
I'd rather add solid vets to a VERY good core of young guys ainge has lined up:
rondo, bradley, lee, green, sully
then draft guys who are

ok in a weaker draft
