I think this will be the closest the west has been in years.
Auburn is the only team out of Auburn, Bama, and LSU that I expect to be better this year than last year. They may not be much better than they were at the end of the year, but they should be a much more consistent team that doesn't require an insane streak of luck to stay undefeated. I could see Bama and LSU taking a step back to being even with MSU based on what they're losing, but based on hwo they have reloaded the past five years, I think the safer guess is that they will continue to be top 5ish teams that have just enough turnover to keep them from going undefeated and likely not even 11-1. A&M I could see being as high as second based on their recruiting, but would guess they will be sixth based on how their defense played last year (provided neither MSU nor UM are hammered by key injuries).
I could see this being a year where nobody makes it out of the west with fewer than two SEC losses. I expect the winner of the west to have two losses and to win on a tie breaker because one of their losses was to an East team.
