Actually, you'd be hard pressed to come up with a game where Greg was consistently double teamed during the last month of the season. Also, he would draw most his fouls off of offensive rebounds on drive & dish situations.
I'm not saying to not look at him at the offensive end, go to him against an obvious mismatch, or run a low screen across for him (as we didn't last season), but that going to him on offense should never be a part of our gameplan. His ability to weakside rebound and occupy a defender makes him plenty valuable on the offensive end as is.
