I am not sure if AM can beat out recruit Cooper Bateman, I think is his name.
Here's a quote from the link:
Morris was always a developmental project but even if Cooper Bateman is the future Morris has a chance to lock down the #2 spot long term which would make him "the guy" in the event of an injury.
Appears Morris is projected as a permanent backup. CB is one of three QBs in class of 2013, probably the most natural talent.
I still like Sims as a backup, at least for now. He showed some promise running the wildcat with reserve players, didn't make many mistakes, and adds a new wrinkle. I don't know if he could do it for a whole game though.
