I stated in the prediction thread that his play has just gotten worse and worse since his freshman year. He's not quick enough to be a corner and not physical enough to play safety, and I think this staff has him trying to do both of those roles at the same time. That "pick route" against Hollywood, as Lowell said during Longhorn Rewind, was a MISSED pick route that PJ just wasn't reading well enough to follow. Thank goodness for Brandon Jones and BJ Foster picking up some slack last game, otherwise we lose.
The problem is that I don't think we have anyone who can play that nickel-hybrid position, or at least not without some cross-training. Boyce got killed in his limited playing time early. Thompson and Estell would be likely candidates but are probably miles behind Locke in experience. My other thought was Chris Brown.
