Yeah, I'm worried, too---we sure as hell found a GEM in Trey. One thing that might help keep him from bolting now is his height. There are very, very few guards in that league who are 5-9...regardless of talent level.
Re: Sully, I can't see him returning to OSU. He's seen what coming back for one more year has cost him already, and there's another 30+ games of injury risk if he does return next season.
An aisde on Sully: gotta hand it to him, comporting himself classily (much unlike his school's average fan) last night in Minny. The Gopher guy "in-bounded" the ball smack into his (Sully's) chest, point-blank...and surely looked intentional...had to hurt. And JS just closed his eyes, shook his head, and moved on (his team was comfortably ahead, and a "T" would not have cost them the game)
