I think the problem may be deeper than this, sadly. Frankly, I just don't think Gillon is very good. Frank is better, but is inconsistent and erratic. Andrew White looks like a one trick pony. Decent spot shooter, but can't make his own shots off the dribble. I don't know what Lydon's deal, but I actually think his best college position is at the 5. I'm not sure if he will be able to play the 3 in the NBA (hence I don't think he will leave early). Roberson is terrible offensively, and all of a sudden, is ineffective on the boards.
Again, there is virtually no movement on offense and almost no low-post game to speak of. Things are not looking good,
