Let's keep this simple. It was an ass-kicking from start to finish. Congratulations to the Crimson Tide. LSU was never in the game, not really.
On offense, they looked like they installed lead weights into their shoes before the game. They only made 92 total yards and only penetrated Alabama territory once.
The defense was not much better.
Final score: 21-0.
Five field goals, one touchdown with the extra point blocked.
