MIAMI -- Eddie Lacy and No. 2 Alabama bashed No. 1 Notre Dame to start the BCS championship game, scoring touchdowns on its first three drives to take a 21-0 lead one play into the second quarter Monday night.
The Crimson Tide (12-1) marched down the field with ease on the opening drive, going 82 yards on five plays to take a 7-0 lead on Lacy's 20-yard touchdown run up the middle with 12:03 left in the first quarter.
Notre Dame (12-0) had allowed only two rushing touchdowns all season.
Notre Dame did nothing to respond and on its punt back to Alabama, the Crimson Tide might have caught a break. Returner Christion Jones muffed the kick, but Notre Dame was flagged for interfering with the catch, though it was one of Jones' teammates that made contact with him.
Lacy and the Crimson Tide went right back to work, hammering away at Notre Dame's vaunted defense. The Irish struggled to bring down the 220-pound tailback, who even ran through Heisman Trophy finalist Manti Te'o on a screen pass.
Lacy popped another 20-yard run that got the Tide down to the Notre Dame 2. Instead of running into a Notre Dame goal-line defense that has been one of its strengths all season, AJ McCarron faked a handoff and found tight end Michael Williams all alone for the score and a 14-0 lead.
Alabama made it 3 for 3 on the next drive when T.J. Yeldon scored from a yard out on the first play of the second quarter.
The Alabama fans seemed outnumbered at Sun Life Stadium by Fighting Irish followers, but they were making all the noise as the Tide rolled.
Notre Dame had only one first down and had already allowed 203 yards. The Irish defense came in allowing 286 per game.
Lacy had 72 yards on eight carries and McCarron, the MVP of last year's title game against LSU, was 8 for 9 for 112 yards.
Alabama was trying to become the first team to repeat as BCS champions, and to win its third in four seasons.
