In my oversimplified analysis of LSU football, O-Line play has been the difference between us and Bama over the past four years. They've gotten more out of theirs, which has allowed better RB and QB play, and been the difference in our games with them.
You have to remember that we had two tackles that were on most of the preseason all conference teams. one on the first team and one on the second team. Both were gone by the Florida game.
We also lost one of our starting guards, in the Florida game, to concussion.
I don't think it takes a rocket scientist to conclude that losing 60% of your starting OL can have a negative impact on your performance.
Other important factors were the loss of the Honey Badger impact plays and our passing game struggling at times.
