The point I'm trying to make is, Bonzi doesn't stretch the defense, so everyone clogs the lane. If we had a Shooting Guard who could step out and make the 3, like Raja Bell or someone who can hit it consistently, we'd be a lot better off. This forces your man to stick with you and frees up double teams in the post, making Artest/Shareef's job easier. Instead, you have Bonzi trying to work it inside too. Most of Bonzi's game is inside, not jumpshooting.
Also - don't bring up QRich, he's been hurt all year like Kings113 said, and he's playing on a messed up Knicks team. Joe Johnson didn't excel just because he was in the Suns offense with Steve Nash, he's been great all of this year as well.
