That feels like wishful thinking. Players have trouble staying healthy for a full 17 games playing 1 position. Players have trouble keeping their bodies from getting worn out over 17 games, let alone the post season.
Thinking a player can do both, especially a rookie while staying healthy and keeping the body fresh seems like nothing more than wishful thinking. I think most teams are going to have him on the draft board as a single position which hurts his draft stock. Because while he was a very good CB, he wasn't lock down even against bottom of the barrel college offenses like KU, KState and BYU (BYU I'm guessing, I didn't watch that game).
