There isn't another non P5 school that could sustain itself on it's own revenue alone. The 12th school would have to go independent, like BYU has, and hope they could get deals and draw attendence everywhere just like BYU. It would be a major risk for that 12th team to join, and it sound like this would be for football only, and search out a contract with ESPN or some other network. One thing that makes Independence work for BYU is BYUTV. No other school can compare to that as well.
