LSU has already proven this year that it can beat good teams and play very impressively when they need to. Many feel that Notre Dame is yet to do that. In this respect, from a sheer football standpoint. I feel that Notre Dame has more to gain from a win than LSU does. Notre Dame will have a daunting task in front of it though. Russell is one of the best quarterbacks in the nation. And if LSU's offense shows up in a big way against Notre Dame, it could be a long day.
LSU's two losses were more because they couldn't put enough points on the board, than because of a suspect defense. (i.e. a 7-3 loss to Auburn). Notre Dame's problem has been the opposite, and inability to stop high-powered offenses. Like many of these games that stack a great offense against a great defense, the winner of the game is normally the one that wins the other side of the battle. In this case, LSU's offense against Notre Dame's defense. I think LSU has the edge here. But special teams and turnovers will undoubtedly play a big role. As these two teams are a comparable match.
