I thought I had brought this up before. Even tho McCaffery is the better of the backups it will all depend on AM's health and the team's record. If Am goes down for the season at mid way and the team is undefeated I think you throw caution to the wind and burn Mc's redshirt. But if there have been a few losses already you probably just play him in the last 4 games if there is an opportunity. I'm sure they have probably worked out the situation where they would have to burn it.
