You certainly would know more than I. However, a few years back here in Charlotte, I worked with an LSU fanatic...great guy. We actually went to an LSU game together, a night game in Death Valley...a 14 hour road trip. It was awesome! He gave me a lot of history, his version of why Baton Rouge is the true Death Valley and how Tiger Rag is also first to the Bayou Bengals vs. your cousins to the northeast in Clemson.
He also talked about the white vs. purple jerseys...I don't recall it being just because of the heat, but I really don't recall much from that trip between the beers and Crown Royal, his drink of choice.
I believe LSU annually closes its regular season games with the Razorbacks...that is always a Friday game after Thanksgiving. I don't think I've even seen LSU wear their purples then or really anytime (when it's up to them)...even when it's cool out.
I'm not a fan of the SEC, I guess it goes back to the '87 Sugar Bowl and Pat
Tie Dye being the reason. However, although today I'm really not in touch with my once upon a time LSU colleague, I often recall that great experience and road trip he took me on...and often find myself routing for LSU.
