for this team, no. the team needs a great PG because well, we already have Pierce, Allen and KG. i will not be starting Griffin over KG because KG has been the DPOY this year, in my eyes. i would also rather win a championship now (and maybe next year) rather than have Blake.
but if we can package Rondo with say, Baby and Nate or something, and get Blake Griffin and still get a decent PG (someone had mentioned Billups) then i say we do it. Even getting a PG like Baron Davis wouldn't be so bad. I realize Baron's stats have been horrendous and he's been out of shape but i think it's all just "motivation" for him. He sulks and plays with no heart when his team sucks. But when he actually plays motivated (something i'm sure this new Celtics team with KG, Shaq, Pierce, Allen), he produces! as a matter of fact, he's producing now because Blake has gotten him pretty excited about playing again. and i'm sure he can be coaxed into playing D as well.
but if in a completely different scenario, and our team was rebuilding or on a youth movement, then i am saying yes.
