CHARLOTTE, N.C. -- Jameis Winston and No. 1 Florida State made it look easy again.
The Seminoles are headed to the BCS national championship game after one of the most dominant regular seasons in college football history.
"This whole week has been very high emotion," Winston said. "We wanted to win this championship so bad. We were looking forward to having an undefeated season."
Two days after prosecutors decided not to press charges against him in a sexual assault case, the 19-year-old redshirt freshman threw three touchdown passes and ran for a score, and Florida State stormed into the title game with a 45-7 victory over No. 20 Duke on Saturday night in the ACC championship game.
The Seminoles (13-0) are expected to face Auburn in Pasadena, Calif., on Jan. 6 after No. 2 Ohio State lost to Michigan State.
The Heisman Trophy favorite was 19 of 32 for 330 yards and set FBS freshman records for TD passes (38) and yards passing (3,820) in a season.
Winston threw two touchdown passes to 6-foot-5, 234-pound receiver Kelvin Benjamin and ran for a 17-yard score to overcome two interceptions.
"The football field is our sanctuary," Winston said. "Every time I stepped on the field, every time we stepped on that field, everything that happened outside of our family, it was just zoned out."
As Queen's "We Are the Champions" was playing as a backdrop on the celebration, Seminoles coach Jimbo Fisher said: "We're not champs yet."
Florida State's defense was dominant, holding Duke (10-3) to 239 yards and forcing three turnovers to help the Seminoles win their second straight ACC title. The Blue Devils had eight possessions in the first half and failed to pick up a first down on seven of them.
"Offensively we were out of sync early," Fisher said. "Our defense was the key tonight and they were absolutely outstanding."
It was Florida State's 12th win by at least 27 points. The Seminoles entered as 29-point favorites after outscoring its opponents by an average of 43 points.
Florida State outgained Duke 569-239.
Winston struggled early with overthrowing receivers and the Seminoles failed to score in the first quarter for the first time this season.
Florida State's first scoring opportunity ended when Devonta Freeman coughed up the ball at the Duke 3 following a 22-yard run.
But it wouldn't matter.
Florida State slowly took charge in the second quarter and built a 17-0 halftime lead behind a stifling defense.
Winston got the Seminoles on the board early in the second quarter when he found Benjamin for a 14-yard touchdown pass in the left corner of the end zone. Karlos Williams bowled over two defenders on a 12-yard touchdown inside run to make it 14-0 after Lamarcus Joyner intercepted Duke quarterback Anthony Boone's pass.
The Blue Devils simply couldn't move the ball in the first half and were held to 94 total yards.
Given enough chances, Winston finally made them pay.
"I don't know if we were demoralized," Duke coach David Cutcliffe said. "It's no fun, but we competed with them. We were on the field a little too much. You know going in that a big, strong quarterback that moves around well will extend plays, so you have to maintain your discipline in coverage -- and we did for the most part. But their defense does a good job of getting the other offense off the field, and unfortunately that worked well for them tonight."
The onslaught continued in the second half with Winston hooking up on a 54-yard touchdown reception with Benjamin, who showed he's not only big but can move too after blowing by defenders. He finished with 119 yards receiving.
Freeman ran for 91 yards and a touchdown and Williams had 59 yards on the ground.
Winston, a redshirt freshman and the game's MVP, was far from perfect.
He threw two interceptions and also made a bad decision on a shovel pass as he falling to the ground. The ball hit linebacker Kelby Brown in the hands, but he couldn't corral the ill-advised pass.
There was a heated moment midway through the fourth quarter when Winston took exception to what he felt was a late hit on the Blue Devils after he released a pass.
Duke's only points came with 1:01 left when Josh Snead scored on a 5-yard run.
Boone struggled all night for the Blue Devils and finished 20 of 40 passing for 138 yards with two interceptions and one fumble leading to 14 Florida State points.
Despite the rough night, his sprit wasn't broken.
"This has been one heck of a year and we'll definitely be back here next year, I promise you that," Boone said. "And we've still got a bowl game to win. That's still one of our big goals for the year. We went to a bowl game last year, got a taste of it, but this year we want to leave with a victory and finish this year 11-3."
Said Duke defensive end Kenny Anunike: "This doesn't define our season."
NOTES: Jamison Crowder set a new Duke single-season record in yards receiving in the first quarter. ... Florida State kicker Robert Aguayo set a new ACC record with 142 points on the season when he converted a 45-yard field goal late in the second quarter. ... Duke sophomore safety Dwayne Norman was flagged for targeting a receiver with his helmet and ejected in the fourth quarter. He will not be eligible to play in the first half of Duke's bowl game.
