They're ranked (even if perhaps overrated) and we are not. They have the revenge motive, we don't. They will have an insane crowd (despite the small-ish stadium), and we will have to fight through that. They have the "history" of wins there (despite there being so few games there), such as: 1992 (yes, I remember it) and Shane's insane 6 picks in a 30-6 loss; SOS's 2000 loss where they tore the goalposts down and injured our team manager; 2004 the nail in the Zook's coffin; although our last game there was a win - Timmy throwing a pick-6 and still winning three games after his concussion in Addazio's decrepit offense in 2009.
Probably all of these angles will be played up on TV (and radio, and print) prior to, and perhaps during, the game. And at 3-1, a win there means LSU on CBS (with Timmy being inducted into the RoH), probable ranking between 25 and 20, and a BIG game at home.
So yes, this really does seem like a turning point kind of game. Win it, and instant "recognition" and "respect" all of a sudden come our team's way.
