They (singing Harbaughs) still need to beat y'all Big!
First, why? What fans say does not impact the game. It is better to believe than worry.
Second, Alabama has 36 sacks so far this year - same as Clemson. Care to guess which defense has faced tougher offensive lines? Yes, Clemson gets after the QB, but Tua and Jalen will both be 100% for that game, and you beat that same front 4 with Jalen at QB last year.
The only team that worries me is Michigan. That defense is good from front to back, sideline to sideline. More importantly - they are playing with an attitude. IMO, that is one defense that will hurt your QB to win the game.
