re: In the next 15 years, do you see Bama ever losing 3 or more games in a season?

Absolutely. Once Saban is gone, it's not going to be even close to the same program. Don't get me wrong. They will still be very good. They just won't be nearly as dominant as they have been. They will have many 11/1 and 10/2 seasons with some 9/3 and even some 8/4 seasons tossed in rarely.
