What chance does Virginia Tech have to upset LSU this weekend?

Virginia Tech has a good chance to me. Their defense will keep the game close. And their conservative offens does not make too many mistakes. This very well could end up a defense stalemate type of game. I think it's up to their special teams to make a big play. I feel like all Sean Glennon can be expected to do is manage the game and don't make mistakes. They can win this game. And how great of a story would that be? Maybe greater than Appalachian State over Michigan.........who knows?
