Notre Dame has a really good defense, which is an asset in the quest for a National Championship. This ND team is different than ones of past years and BCS defeats because it is grounded primarily on a good defense and an average offense. All good offenses can be stopped by a physical defense. In fact, when a good offense meets a good defense, the defense usually wins. In this case I would expect the game to be close. Alabama is a ten point favorite, which seems quite high. Regardless of who is #1 vs #2, that is a big point spread for a football game, and probably reflects more of Alabama's past accomplishments and success, and Notre Dame's recent failures than anything else. But this is a new team, removed from the Brady Quinn era and the Charlie Weis era.
Who will win? We can never know with certainty.
Should 'Bama be a 10 point favorite? No.
