DoL probably takes blame for the Trey pick, as he should, the buck stops with him. Corbin, theoretically, spent the year coaching the team, it was up to DoL and his staff to handle the scouting for the draft. So to let Ty come in and override the whole scouting dept doesn't make sense to me. My guess is that DoL liked him as well. That's not a stretch, considering how 90% of this board was hot after Trey too. It was only the prescient few such as I who called it that Trey would be Jameer Nelson at best. Dang I'm good.
Having said that, I'm pulling for Trey to make a big leap.
