BYU guy here...I'm a little nervous for this game

First off, just wanted to say that I always root for LSU, especially when y'all play Alabama. I need to see an Alabama vs LSU game in Baton Rouge at least once just to experience the greatest atmosphere in college football.

I'm a little nervous for this game, not necessarily about the W/L result but more how it will effect how we play against Utah and Wisconsin following in weeks 2 and 3, our schedule is brutal each September and I'm not expecting a W in this game (but really want to beat Utah and Wisconsin at home). LSU has some defensive athletic freaks and always has had them so keeping Tanner Mangum healthy to play against Utah and Wisconsin is certainly a concern which leads me to ask about Arden Key, is he likely to be eligible? I was reading chatter about him possibly not playing this coming season but wasn't sure what was the latest on that. To me this game has a similar feel to our 2009 game against Oklahoma, except LSU is always more physical (and more athletic?) then Oklahoma so I am expecting a low-scoring, hard-fought game (BYU can also surprise folks with our physicality due to our Polynesian players). Anyways, this game will be an interesting test to see how our teams have improved and to see how it affects our 2017 season going forward. Go Cougars!
