Based on his physical build, he's not explosive enough to operate at WR, and would look better at the TE position.
He has strong, thick legs, and if he used them to drive block, I think he would do better there.
At this point in time, though, I'm fine with his staying at QB as a backup for the rest of the year. He graduates this December, if I recall correctly, and can re-evaluate things after the season.
