Here's my take on everything as it relates to Royce, Trevor and Al.
Al will definitely be back in the mix next year. If he can't get his academics straightened out between now and the start of fall practice next season, then there is little hope for him. Therefore, it seems like a given, at least to me, that he'll be here next year.
I feel close to the same way about Trevor. Of course, his situation is different because without the legal issues, he would have been eating up minutes from the start this season. On top of that, he's been solid with his practice and in the classroom according to some folks. Therefore, if things work out for him legally, he also should be in the mix next year. But there's the rub: it's either going to be he's incarcerated or playing b-ball for the Gophers imo.
Royce is like the ultimate wild-card. Through all this mess, it's pretty obvious he still has a case of "Gophers on the brain." Therefore, I wouldn't completely rule him out either, although any more shenanigans from him would cause everyone to have a mental breakdown.
Now comes the interesting part. Apparently, the Gophers are looking to still sign Cory Joseph and possibly another JUCO player, which would effectively eat up Royce's scholly. If that happens, Royce doesn't strike me as the type that would walk-on.
So, taking everything into account, I'm thinking that we'll have Al and with a little luck, Trevor. Not counting on Royce at all, but hey, stranger things have happened.
