Addressing the media while attending the Senior Bowl, Saban said, "I think we have a young quarterback who definitely made some progress last year who we have to give an opportunity to in the future to see if this guy can elevate his play, leadership, ability to execute with consistency, taking care of the ball and do all the things that a good quarterback needs to so we can have success in the future.
"I think quarterback is a critical position. I feel that evaluation needs to be continued and is ongoing."
I truthfully don't see anywhere that Saban is stating that AJ is the unquestionable starter, I see that he plans on giving AJ the chance to see if he can improve his play, What do you suppose will happen if AJ does not improve.
Besides do you really expect Saban to come out and say AJ sucks and is going to be replaced(Like Dave did with Jay), then find out they can't find anybody better and have to fall back on AJ. I don't think that would go over to well with AJ.
I think the best option is to give AJ a chance but have somebody else in camp to at least compete and give them another option if AJ doesn't improve.
