We really need size off the bench.
I love Perk and we're lucky to have him, but he gets in foul trouble a lot and his shoulder keeps getting injured.
Pretty much all of our players are undersized (except KG). Rondo, Perk, Powe, BBD, and Pruitt are undersized.

(Ray and Paul are on the small side, too.)
Why didn't we draft Hardin, or some other big guy?
What happens if we have to face Dwight Howard or Ilgauskas in the playoffs next year, and Perk and KG are in foul trouble? Put two 6'8" players on them?
I don't think Ainge is finished yet. But as I look at the free agent bigs, I'm not impressed. Diop? Pollard again? Kwame Brown

? Brezzec? Kurt Thomas (he's too small)? Skinner (maybe)?
I don't think we can repeat if we don't get a defensive 7 footer.
