I think Sims did a good job and will only get better and better. I wouldn't read too much into Cokers body language. He'll be the starter next year.
I do like the fact that it seems Saban didn't go to the kid and tell him the job was his. He had to earn it. Greise said that Coker looks good in 7 on 7's but has to think too much when going live with all 22.
