Alabama is unbeatable. So is Notre Dame.

If you're going by the numbers, that is. After 12 or 13 games in 2012 and another two-plus years under their respective head coaches, both the Crimson Tide and Fighting Irish have hit certain markers that essentially guarantee victory.

DOMINANT: 'Bama owns the SEC, the FBS and the NFL Draft

For example, Notre Dame is 24-1 under coach Brian Kelly when allowing less than 20 points. Alabama is 49-0 since 2008 when rushing for at least 150 yards. More fun with numbers:

-Notre Dame is 16-2 under Kelly when winning the time of possession. That's been a major key in 2012 (9-0), thanks to the Notre Dame running game and the ability of its defense to keep opponents from converting on third down.

-Notre Dame is 5-0-1 when the No. 1 team in a No. 1 vs. No. 2 pairing. The Irish are No. 1 in every poll, while the Tide come in at No. 2.

-Alabama is 61-3 under Saban when leading at halftime. The lone losses came to LSU (2007 and 2010) and Auburn (2010).

-Notre Dame is 23-2 under Kelly when outgaining the opposition on the ground. (Conversely, the Irish are 4-9 when outgained on the ground.

WHO HAS THE EDGE?: Both Alabama and Notre Dame feel confident heading into Monday

-Alabama is 33-2 since 2008 when throwing for 200 or more yards.

-Notre Dame is 5-1 all-time against Alabama. Four of the five wins came between 1973-80. The lone loss (28-10) came during a regular season game in Tuscaloosa in 1986.

-Alabama is 24-0 under Saban when converting more than half of its third-down tries on offense.

-Notre Dame is 16-1 under Kelly when winning the turnover battle. After struggling with turnovers in 2011, the Irish have done a far better job protecting the football this season.

-Kelly is 6-0 as an FBS head coach against teams whose names begin with the letter "A," beating Air Force (2011), Army (2010 and 2005) and Akron (2008, 2006, 2005). He's 14-0 all-time against such teams, including his stint at Grand Valley State.
