It strikes me that the main problem with our bench is simply youth. Three of the 4 guys coming off the bench are freshmen and the fourth is a sophmore. We've obviously been hurt by the transfer of various marginally talented players who could still have served as effective role players off the bench. I'm not sure any of these guys would have been a sparkplug on offense (which is something we desperately need) but they would at least not be the offensive liability our current 4 guys are.
Seeing as youth is the problem, I don't think we're fixing the problem this year. Given some time I think Benimon, Sims, Thompson, and Sanford develop into good players capable of playing supporting roles either as starters or off the bench rotation
I see Thompson developing a few more offensive moves (he definitely could work on his shot creation ability) and becoming a reliable 8-10 points a game player.
Benimon could definitely develop into a useful Vaughn-like power forward that would help shore up the defense and be a powerful rebounder and shot blocker.
Sims needs to develop his defensive footwork a lot more (he gets caught off-position a lot) and also needs to develop his post up game, but could probably develop into a 10-12 points a gamer.
Sanford if he developed a little further on offense could provide a useful offensive spark. Unlike Hollis, he seems to be a bit more comfortable driving into the lane, so the possibility is there.
You add in Starks and Lubick next year, along with another year of development for these 4, and if our big 3 stay at Gtown, I think we are a force to be reckoned with.
