I wish I shared the same feelings as you all on the blowout scores.
LSU has a lot of offensive firepower and while our defense has improved by leaps and bounds since A&M, I'm not certain our secondary is as settled as it needs to be. Losing Vinny really hurts in a game like this too. Plus there is the Les Miles factor as has already been mentioned. Doesn't matter how uneven LSU looks all year long, they will always play their best against Alabama (unless the game is in New Orleans).
If we can shut down or slow down their running game with Hill, we'll be well on our way to a win. Also, don't turn the ball over. Our offense ought to be able to put up the points as long as we don't turn it over (ball security, RBs!)
Score? 31-21. It's going to be a hard fought game.
