Bucks question?? larry sanders rookie?

why arent the bucks playing him much. hes shown good. hes had a couple 7 block games, had a couple 15 point games, good shooter, ggood defense but why do they play brockman instead of him. brockman really only fouls people and plays defense, but i like sanders and bogut combo. plus jennings has 3 more ists when sanders starts, opposed to when gooden,illasova,or a moute starts
