TUSCALOOSA — Opponents of the BCS and advocates of a college football playoff are in for a treat Saturday.

Math and logic create an unofficial bracket that starts in Tuscaloosa.

Third-ranked Alabama’s 2:30 p.m. date with No. 9 LSU is a de facto national quarterfinal game given records and rankings. A Crimson Tide win guarantees a second straight trip to the SEC Championship Game to meet Florida, which clinched its spot with a win over Georgia. And with the Tide and Gators near the top of the Bowl Championship Series standings, the winner of that potential match-up is assured a plane ticket to Pasadena for the national title game.

Only LSU (7-1, 4-1 SEC) can muddy the waters for the Crimson Tide (8-0, 5-0).

A Tiger win Saturday would give both teams one loss atop the SEC West, but LSU the tiebreaker with a head-to-head win. The Tigers’ only setback came against No. 1 Florida, which snuck out of Baton Rouge with a 17-7 win Oct. 10.

Throw in the history Alabama coach Nick Saban has with LSU, and Saturday’s nationally televised game has all the makings of a classic.

Just don’t mention that to Saban.

Trying to get ahead of any such questions, he tried to downplay the hoopla surrounding Saturday’s game before taking questions from reporters at his weekly Monday news conference. He even borrowed a quote from New York Yankees manager Joe Girardi to illustrate his point.

“Girardi said ‘to close out the (World) Series, I want to play good baseball.’ What gives you the best chance to close out the Series? Play the best baseball you can play and keep playing the best you can play,” Saban said.

When a reporter asked about the SEC title implications several minutes later, Saban didn’t wait for the question’s conclusion before showing his agitation.

“Do I need to repeat it again?” he said after reiterating how little he thinks of the meaning of the game.

Regardless of how much it’s down played, the stakes remain. And they’re hard to ignore.

“It just so happens that this next game’s a pretty big one for us, pretty important,” senior offensive lineman Mike Johnson said. “I think everybody’s going to be at a little higher level. I mean, it is LSU week. This is always a big game around here, especially in the last few years.”

Ignoring the pregame build up isn’t too hard, linebacker Rolando McClain said.

His reason is simple enough.

“We’ve got coach Saban,” the Decatur High grad said. “It ain’t very hard. He keeps us focused, and we’ve got good leadership that keeps us focused. It’s a one-game season. That’s how we’re going to take it.”

Like Saban, LSU coach Les Miles doesn’t see the need for motivational speeches this week. He too faced questions about the intertwined coaching tree when meeting with reporters in Baton Rouge on Monday.

“I don’t think we need to put other pretense on this game,” Miles said. “This is a game that is very significant, and our guys understand it.”

If Alabama has an advantage Saturday, it’s going to be in their legs. Having a week off following the 12-10 win over Tennessee Oct. 24 was incredibly beneficial, several players said Monday.

LSU beat Tulane 42-0 on Saturday — two weeks after its Saturday away from competition.

A top 10 matchup

A look at a few important recent meetings between Alabama and LSU:

1996: In Gene Stallings’ final trip to Baton Rouge, La., as Alabama’s head coach, the No. 10 Tide rode 291 rushing yards from Shaun Alexander to beat No. 11 LSU 26-0. Alexander’s mark still stands as a school record.

2002: No. 10 Alabama, led by then-coach Dennis Franchione, won 31-0 in Baton Rouge and handed No. 14 LSU its worst home loss during Nick Saban’s five years as the Bengal Tigers’ head coach.

2005: In perhaps the biggest game of the Mike Shula era at Alabama, the Tide entered unbeaten and ranked No. 4, while LSU was once-beaten and No. 5. LSU won 16-13 in overtime.

2008: No. 1 Alabama defeated No. 16 LSU 27-21 in overtime in the Tide’s toughest test during an unbeaten regular season.

2009: No. 3 Alabama faces No. 9 LSU with a probable spot in the SEC Championship Game on the line. The Crimson Tide is 4-1 in the series when both teams are ranked in the top 10, and all four of Alabama’s victories came when Bear Bryant was coach.
