NEW ORLEANS — The Rematch of the Century, it wasn’t.

Alabama romped to another BCS championship against top-ranked LSU with a smothering defensive performance, a numbing barrage of field goals and even a long-overdue trip to the end zone.

Good enough for No. 1, if not a lot of style points.

No. 2 Alabama posted the first shutout in the 14-year history of the BCS, relying on Jeremy Shelley’s right leg for most of the points — he made a bowl record-tying five field goals — and letting its defense do the rest. The Crimson Tide romped to a 21-0 victory over the Tigers for its second BCS title in three years.

While only crimson-clad fans will remember this one as a thing of beauty, Alabama (12-1) erased any doubts that it deserved to be in the title game over another one-loss team like Oklahoma State or Stanford.

Then again, one of those teams might have actually scored a touchdown before Alabama finally did, with 4:36 left in the game, long after fans may have flipped to something more entertaining than a one-sided kicking contest. Amazingly, these Southeastern Conference powerhouses played twice in a span of about two months, and never came that close to one of those things that’s worth six points — you know, touchdowns — until Trent Richardson broke off a 34-yard run with 4:36 remaining.

It only took 115 minutes, 34 seconds, plus an overtime period in their first meeting.

LSU (13-1) had beaten eight ranked teams — including Alabama in early November — to establish itself as the clear No. 1 going into the bowls, but the Tigers crossed midfield only once in the sequel to the Game of the Century in Tuscaloosa. Instead of putting up a “Godfather II,” this one was more akin to “Speed 2.”

The Tigers were outgained 384-92 in total yards, managed a puny five first downs and didn’t cross the 50 until there were just 8 minutes left. From there, they went back, back, back — the last gasp ending appropriately with beleaguered quarterback Jordan Jefferson getting the ball knocked from his hand before he could even get off a fourth-and-forever pass.

The BCS title belongs of his own at the school that still worships Bear Bryant as if he just retired yesterday. The Associated Press likely will follow suit by bestowing the title on the Tide when its poll comes out early Tuesday, given the dominance of Alabama’s performance.
