big mistakes and key turnovers to beat *any* of the top-15 SEC teams. I would prefer BYU to play Oregon, Penn State, Notre Dame, and Miami way before I would want to face Alabama, Georgia, Ole Miss, Tennessee, or Texas A&M. (I would also put Ohio State in this category)
Sure, there are built-in advantages for the SEC as you state...but they all have another level of talent which is their biggest advantage and, frankly, causes most of the bias.
