Robbins leaving for the NFL was a colossal mistake. I think Roberts will fair better, but it is no guarantee. Can we convince him to stay and be the feature deep threat? I know that this is Jojo's current role, but one 2-3 drops/misses by Jojo that cost us leads/games, I think Chase makes those.
I think another year as a sure handed deep threat makes him all Big 12 (maybe more?) and really lifts his draft stock. It isn't high enough now, at least, not close to what it could be.
Retzlaff is going to get better as well and that bodes well for Roberts.
