Here's the thing, whether Benny plays 30 minutes or 0 minutes won't be the difference in him improving his game. It might make him happy and it might make the fans happy, but development comes through drills, in practice, watching film, and putting the work in. That's what will be the difference in whether Benny is a star or not. Feeling your way through 20 minutes in a game is nice experience, but it's not where you make that jump in improving your game. If he puts that work in, then it will play off.
Otherwise, JBA getting minutes tells me more about Benny's development than Jim. Boeheim isn't doing that out of spite.
Unfortunately, Benny came in with too high of expectations. People expected him to start and be an instant contributor. He hasn't been good enough for that.
