Let me just say generally speaking, I don't see a way around the guy being Milroe right now. Saban actually took a huge risk giving serious playing time to the other two QBs but it was about as much as he could do without throwing the season away to try to see if someone else would emerge. They didn't, so now he has to roll the dice on Milroe.
Having said that, if Alabama loses to A&M then everything changes because the playoff is not going to happen and from that point any other loss means a heck of a lot less. I mean a loss now means no championship, a third loss means? A worse bowl game probably? It just doesn't carry the same weight so I don't care as much what would happen after that and I'm not sure Saban does either, he could take more risks. It's one of the great limitation he has at Alabama, almost every game a championship is on the line so certain things he just can't do even if he wants to.
Anyway, as to the intermediate passing stuff, I thought this was interesting (and does show some hope):
