Why? He is one play away from being the qb when the season starts. He was 2nd on the depth chart, behind Worley. He was ahead of Dobbs and Ferguson earlier in the Spring. Dobbs has passed him, but the coaches thought that he and Worley were about even, going into the season.
If he can get some meaningful playing time behind an improved line, against a team that is not a dominant defense, he can get some confidence, and play football.
It would be in his interest to transfer to an FCS school where he can be the starter all the time and not just come in from time to time.
