ATLANTA — Playing like a team determined to show it should have been included in the four-team playoff, No. 6 TCU rode three touchdown passes from Trevone Boykin and a dominant defense to a 42-3 rout of No. 9 Mississippi in the Peach Bowl on Wednesday.

Josh Doctson had two touchdown catches and Aaron Green ran for a score and added a touchdown reception for the Horned Frogs (12-1).

Ole Miss (9-4) lost four of its last six games. Bo Wallace threw three interceptions, including one caught in the Rebels end zone by defensive end James McFarland for a touchdown.

Late in the third quarter, when the lead was 42-0, TCU fans targeted the No. 1 seed in the playoff when they chanted “We want Bama!”

TCU was ranked No. 3 by the selection committee before crushing Iowa State 55-3 to end the season as Big 12 co-champions. The Horned Frogs were devastated to fall to No. 6 in the final ranking.

What looked like an intriguing matchup of the Ole Miss defense against TCU’s high-scoring offense quickly turned into a rout.

TCU played like a championship contender, scoring two touchdowns in each of the first three quarters.

The action was as lopsided as the score. TCU finished with 423 yards and allowed only 129 to Ole Miss. The Rebels were held to 9 yards rushing in the biggest margin of victory in Peach Bowl history.

Ole Miss ranked first in the nation with its average of only 13.8 points allowed. Turnovers and TCU’s quick-strike offense were too much to overcome.

Wallace completed only 10 of 23 passes for 109 yards with three interceptions.

The Rebels avoided the shutout when Gary Wunderlich kicked a 27-yard field goal with 7:18 remaining.

Boykin also had turnover problems, as he completed 22 of 31 passes for 187 yards with three touchdowns and three interceptions. He had 10 carries for 65 yards.

There were a combined five turnovers in the first half, including three by TCU. Boykin threw two interceptions and wide receiver David Porter fumbled when trying to pitch to Green on a trick play.

The Rebels, held to four first downs and 59 total yards in the first half, couldn’t take advantage of the turnovers.
