He is making a meaningful contribution even if he never sees a minute of court time in games.For a guy whose screen name is an ode to a guy who wasn't supposed to play anything but garbage minutes, I hope you don't hold it against him if he makes a meaningful contribution without someone else getting hurt or the team sucking.
The harder he goes in practice, the better he makes everyone else on the team. There are actually guys who understand that role, and relish it. I'm betting Apostolos is one of them.
