Big Baby could contribute, so he played. Powe could contribute, so he played. As much as we need size right now, if JuJuan Johnson could help this team, he'd be playing. So lay off Doc already. Personally, I think JJJ is terrible and will have the same career that every soft, 6'10", jump shooting PF, who plays no defense and can't rebound has. A short one. The only reason he's on the C's is because of his height. He was just another body to fill a roster spot, at a time when we were desperate for size. In fact, our ENTIRE bench is put together out of desperation. With MAYBE the exception of Pietrus, none of our reserves belong in the NBA, and in four years or less, none of them will be in the NBA.
I assume the people that call out Doc for not playing the rooks are kids. When I was young, no matter how bad they were, the rookies were always my favorite players. Or at least I always wanted to see them play. As I got older, I learned how to evaluate talent a little better, and I understood why the rookies didn't play. For every basket you watch JJJ make, Doc sees him make 5 mistakes that you don't see. Stiemsma, Bradley, Moore and JJJ are not NBA players. So don't get mad at Doc for not playing them in NBA games. Oh, and this link also says you're wrong. Good day, kids.
