re: UCLA: The matchup to watch will be their o-line vs our d-line

Chip's run game switched to more of a gap scheme last season, with lots of pulling, trapping, and unbalanced formations. You won't see them them just lining up and blasting people, the scheme is based on messing with the linebackers' gap responsibilities from play to play. It's a bit like an option team, where you might stop a few plays in a row, but it just takes one linebacker misreading the run fit and you have a giant hole to run through.

LSU should have a physical advantage in the matchup, but UCLA's O-line is very experienced and disciplined, so it will take an equally disciplined and mistake-free effort from LSU to shut the run game down. Should be the most fun matchup of the game as OP said.
