Players like Jaric are a dime a dozen. If they could get a big man for him, especially since C-Webb is going to take up minutes at the 4 now, then I think it is a good move. Jaric does not bring enough to the team to keep him out of trade talks. Plus it would be nice to have more size and another person in the paint to help KG. It is similar to Brand's situation in LA, KG is expected to alter shots, rebound, score, pass, and block shots. If he grabs 5 rebounds one night instead of 10-15, then they get killed on the glass because no one else is there to really help him.
Dale Davis IMO would be a decent pick up. He is a big body that can bang with other big men. KG doesn't really have the body to bang with guys like Tim Duncan...let alone the Eddy Curry and Nene's of the league.
