If we are talking most exciting games, the LSU game was the most exciting if only for those last 2 minutes or so. Man, they just drove down the field .. Everyone at the Bama bar I was at had gone into full silence/praying/looking sad mode, and within the space of about a minute, were jumping up and down with joy. GA was a nailbiter too because of those last couple minutes .. Whew.
But upon reflection .. my favorite has to be ND because it was a beatdown of epic proportions on the national stage. Not to mention it was revenge!
