I think a third alternative is that the players are just not being developed. I think that is where the real difference between Miles and Saban is beginning to appear. Miles won a NC with a senior class that had been recruited by and largely developed by Saban and his staff. Miles was able to continue the recruiting, but player development has declined. Similar to, but not as bad as our Shula ear, Shula got decent recruits in the door, but they did not develop as Div. I football players.
The fact that he hasn't been able to recruit a servicable QB is surprising though. Of course maybe he has and the issue is coaching again.
