I don't want to disparage Morris, but let's be clear on this. Morris never, at any point has shown that he's ready to start at Alabama. I don't believe he's ever been #2 on the depth chart, and he's not even #3 now. I'm sure he has a great work ethic, he's a great guy, and all of that, but the fact of the matter if he ended up at Alabama after they missed out on who they were aiming for. He wasn't heavily recruited by anyone, he's never blown anyone away, and he's the type of guy that you want around in case others get injured. I would be very surprised if he in fact stays around and takes up a scholarship next year, as I still doubt he's even the #2. I never once got the talk about Morris any more than I got the talk about Ely. Both were plan Bs and ironically FSU in each case got the QB Alabama wanted.
As far as Coker, Alabama recruited him initially (ahead of Ely), and he's taller and faster than AJ. He might not turn out to be great, but he's both considered a pro prospect and one of the best backups in the FBS. Compared to Morris there's really not much of a comparison, the reason Coker wasn't more heavily recruited and more highly ranked is because he was a late bloomer. Put it this way though, Coker was the #2 at FSU, and Morris is at best the #4 right now.
