Durham may redshirt, but it's far from a given. You also didn't mention Jackson, who is going to play the 4. So that's at least 3 other players, maybe 4, that he's going to have to compete with for minutes. If he was a top-10 player, I would agree that he shouldn't be worried, because that talent level is likely going to get the most minutes, but if he's ranked in the 70s? Chances are he doesn't see more than 10-15 minutes a night.
I never thought this kid was a great fit based on what we have coming in. I'll take him if he wants to come here, but if he did I guarantee at least one frontcourt player would be transferring in 2017. I'm much more hopeful for Vital and maybe another guard.
