A massive enthusiasm gap is just an excuse. Nothing more. If Florida State doesn't want to be there, then don't come & forfeit the game. How about that? They'll show up, though.. They want the $$$ for the game, so they can accept their loss (if that's what happens) & not have an excuse of not being "up for beating up Northern Illinois".
Any team that doesn't want to be in a BCS game, regardless of who they have to play.. doesn't deserve to be there to begin with. I don't care if that's Florida State, Florida, LSU, Alabama, Oklahoma or any other big school.. You want the $$ for being there, so accept that you may just get upset & deal with it without people making the "poor Florida State, they only got to play Northern Illinois" excuse. No, poor Northern Illinois.. They play in a game where they won't get any credit, regardless of the outcome.
