Gainesville, Fla. ? Florida starts the passer and brings the runner off the bench. LSU starts the runner and brings the passer off the bench.

Although the schemes and substitution patterns differ, both teams will use two quarterbacks when the 14th-ranked Gators host the 12th-ranked Tigers tonight — even if it makes them a little predictable on offense.

Florida coach Urban Meyer is doing it because he wants to. LSU’s Les Miles is doing it because he has to.

Regardless of the rationale, the adage “when you have two quarterbacks, you don’t have one” might apply to both programs. The Gators (4-1, 2-1 SEC) rank ninth in the league in total offense and pass efficiency. The Tigers (5-0, 3-0) are 11th in offense and last in pass efficiency.

The spotlight has been on the quarterbacks all week for similar reasons, and it will be again tonight in the Swamp.

Florida starter John Brantley threw two costly interceptions in a 31-6 drubbing at top-ranked Alabama and got knocked out of the game late due to bruised ribs. Backup Trey Burton, who scored six touchdowns a week earlier against Kentucky, was stifled on four runs and threw an interception on a fourth-down jump pass at the goal line.

“The one thing that happens when you fail and you fail in a big game, you say, ‘Whose fault was it?’ and ‘Let’s fix the fault,’ Meyer said. “I think everyone wants to know, ‘Whose fault was it? What happened?’ It’s our job to figure it out.”

The Tigers have done plenty of self-evaluation after last week’s near debacle against Tennessee.

Starter Jordan Jefferson, struggling for the fourth straight week, was benched in favor of Jarrett Lee. Lee threw an interception in the fourth quarter, but redeemed himself by directing a game-winning drive in the closing minutes.

Lee marched LSU to the two-yard line before giving way to Jefferson, and then LSU survived a wacky finish to beat the Volunteers, 16-14.
