I have to think that Long, Jackson, and Vault are ahead of him and more comfortable with the offense by virtue of experience. With your assessment of Roberts getting snaps on offense, it's hard to imagine Anderson fitting in with significant reps since we have a solid two deep and will be in a good position to redshirt Moten if we need to.
It's a good problem to have, but according to lonestar, his parents already seem to be threatening a transfer. I have no idea why that would be the case since few freshmen even get to see the field on offense or defense. The only explanation for a transfer would be if they were misled to think that our program didn't have talent and that he came here because he would start instantly. However, very few freshman have played during the Fitzgerald years.
