Fort Lauderdale, Fla. » One day after this year's Heisman Trophy winner quietly slipped into an interview room, looking like an Oklahoma fan dressed in a Sam Bradford jersey, last year's Heisman winner made a star-studded, security-escorted entrance onto Sunday center stage.

"Get off the podium!" a man with a dark suit, wearing an ear piece, bellowed at reporters who were angling for position to hear Florida quarterback Tim Tebow.

No one said whether this man was from Secret Service or Rent-A-Badge, but he sure looked important as he cleared space for one of Florida's most famous.

"It's kind of cool being with a rock star," teammate Louis Murphy joked of Tebow.

The only other time two Heisman winners have faced each other for the national title was four years ago, when quarterback Jason White of Oklahoma and USC's Matt Leinart met under similar BCS circumstances.

Sam Bradford can only hope the score's not 55-19 again.

There's no quibbling with the numbers.

Bradford won the Heisman Trophy this year as a sophomore because he deserved it, throwing 48 touchdown passes against only six interceptions in leading Oklahoma to the Big 12 title.

Tebow won the Heisman last year as a sophomore because he deserved it, accounting for 55 touchdowns by himself. This year he slipped a bit, if you dare to call it that, throwing only 28 touchdown passes (with only two interceptions) and rushing for 12 scores.

Bradford and Tebow, though, are from different personality planets.

Bradford still seems stunned and awed by his Heisman victory.

Tebow, conversely, oozes confidence and pizzazz.

He stirred up Oklahoma this week with an off-cuff remark that he couldn't wait to face a Big 12 defense. Oklahoma's secondary ranks 99th nationally in pass defense. Sooners defensive back Dominique Franks responded by suggesting Sunday that Tebow would "probably be about the fourth-best quarterback in our conference."

Tebow was smart enough to know when not to further a cause.
