Against every other team in the league, his skills are redundant because everything he is good at right now, someone on this team is better than him. The only thing he is better at than everyone else is pick and roll defense, but he becomes a liability on offense because when we put him in there to guard the pick-n-roll, Pop likes to have another floor-spacing big which means Tiago has to play with either McDyess or Bonner, neither of whom are good at protecting the rim, and it means we can't play Blair or Duncan, our two best big men.
Until Pop changes his philosophy (he won't) of having a floor-spacing big man on the floor at all times, Splitter simply doesn't have alot of minutes to play until he develops a mid-range game.
