He was so good he got moved to WR.
When the options are:
1) Sit on the bench and watch Tyler Wilson play all year, while you sit and watch your junior year pass you by.
2) Try to find some other way to contribute.
He chose option 2. He's a natural athlete, so it came easy (stud HS basketball player).
But now that he's a senior and TW is gone, I fully expect he's going to be in the mix at QB. But his move to WR had nothing to do with lack of talent. He had to convince the coaches to let him do it.
