Several updates:
Colin Castleton is also leaving. The hope was he could develop into a similar player as Mo Wagner, but it just didn't happen since he wasn't getting stronger, he was a defensively liability, and he never gained any consistency on offense, either. I wouldn't be surprised if he's successful elsewhere, though, and at least gets a career in Europe.
Mike Smith just committed as the grad-transfer PG, which reduces depth concerns there with DeJulius' departure. It sounds like he's a decent shooter and passer, but we'll see. Jaaron Simmons was a MAC PoTY at Ohio before doing a grad-transfer at Michigan and he never played much as backup to Simpson's sophomore year (Brooks was originally the starting PG as a freshman in November that season, as well), so who knows.
Still waiting on Josh Christopher to officially commit, but insiders are confirming that it's likely to happen next week. That would make Michigan's backcourt pretty strong, with Zeb Jackson as a combo guard, as well.
I think Livers is still more likely to come back at this point.... I'm not even going to try to figure out what Todd is thinking.... Jace Howard is coming in as a preferred walkon afterall, so Michigan could still try to get another grad-transfer if either of them go pro or Christopher goes elsewhere.
