NEW ORLEANS -- Round 2 of Alabama-LSU was more of the same -- except all the field goals were made by the Crimson Tide.

Jeremy Shelley kicked a bowl-record five field goals, Trent Richardson broke free for a fourth-quarter touchdown and the second-ranked Tide's defense smothered the top-ranked Tigers in a 21-0 victory in the BCS championship game Monday night.

The Southeastern Conference rivals met on Nov. 5 in what was dubbed the Game of the Century, and the Tigers won a touchdown-less, defensive standoff, 9-6 in overtime.

In a bowl season filled with high-scoring games, the top two defenses in the nation set the tone at the BCS title game. But Alabama was clearly the best unit, and this time the Tide's special teams were efficient.

Alabama Heisman Trophy finalist Trent Richardson ran for 95 yards on 20 carries, with his 34-yard sprint down the right sideline putting the final touches on the win. A.J. McCarron passed for 233 yards as the Tide didn't have much problem moving the ball -- just getting it into the end zone.

The Tigers finished with 91 total yards on offense.

The Tide claims the BCS Trophy, although it had to wait out the AP writers' vote to see if it won that poll as well.

The Tide's defense was dominant and linebacker C.J. Mosley had the first takeway of the game in the third quarter, his last play of the game as it turned out.

LSU's Jordan Jefferson started to scramble toward the line, but at the last second flipped the ball toward Spencer Ware. Problem was, Ware had turned to block and Mosley snagged the ball and set up Alabama at the Tigers 27.

Mosley was twisted down to the turf by Jefferson and his left leg bent awkwardly. The sophomore stayed down for several minutes and as the medical staff worked on him Alabama fans chanted his first name. As he was carted off, sitting up on the back of a golf cart, he got a huge ovation and pumped his fist.

Alabama couldn't convert the field position into points as Shelley dropped to 4 for 6 on the day, missing wide right on a 41-yarder with 5:38 left in the third. The next time down, he booted a 44-yarder, giving him more field goals than any kicker has ever had in a college bowl game. His seven attempts were also a record.

The Tide, which was 2 for 6 on field-goal tries in the first game against LSU, faked a 49-yard attempt early in the second quarter and went with a shovel pass to backup tight end Chris Underwood that gained 4 yards. He reached the first-down marker by the nose of the football.

The drive didn't last much longer and Shelley's 42-yard field-goal attempt was blocked by LSU defensive tackle Michael Brockers.

Shelley came back to make one from 34 yards with 4:24 left in the half, and from 41 yards as time expired in the first half.

Alabama opened the second half with another solid drive that stalled, but Shelley tacked on another 3-pointer from 35 yards.

LSU offense was shut down completely. The Tigers managed two first downs and 66 yards through three quarters. The Tide, led by linebackers Courtney Upshaw and Mosley, gave Jefferson no space to run the option and only short gains when he passes.

It was Alabama's special teams that struck first in the first BCS title game to match teams from the same conference.

Punt returner Marquis Maze found a lane and broke into the open around midfield, though he pulled up instead of trying to get around punter Brad Wing and grabbed his left leg while running out of bounds at the LSU 26 after a 49-yard run-back.

Maze, the Tide's leading receiver, had to be helped over to the Alabama sideline, but he had put his team in scoring position. Maze didn't play again.

McCarron completed a 15-yard pass to Darius Hanks to set up first-and-goal, but LSU's defense, ranked second in the nation behind only Alabama, stiffened.

Shelley, who made one field goal and had another blocked in the first meeting between the SEC rivals, was perfect on a 23-yarder with 5:00 left in the first quarter.

It didn't sound like an LSU home game at the Superdome, about 80 miles from its Baton Rouge campus. The dome was deafening on almost every play with a crowd that was much closer to 50-50 than partisan.
