FORT WORTH, Texas (AP) — TCU coach Gary Patterson said Trevone Boykin didn't win the competition to quarterback the Horned Frogs' new, up-tempo offense until the team's recent pre-season scrimmages. But Boykin left little doubt that he'll keep it with his performance in the Horned Frogs' 48-14 victory over FCS Samford in the season opener for both teams on Saturday.
Boykin completed 29 of 41 passes for 320 yards. His touchdown passes covered 38 yards to Kolby Listenbee and 19 yards to David Porter. Boykin's scoring run came from 1 yard.
Boykin said Sonny Cumbie, one of TCU's new co-offensive coordinators, told him to simply go out and play his game.
"It was fast, some of the stuff we did related to my game in high school," Boykin said. "It is a much bigger and faster game now, you just have to go out there and respect everybody."
During the past week, Patterson wouldn't say if Boykin or senior transfer Matt Joeckel would start. The multi-talented Boykin moved from quarterback to receiver in 2013, starting the opener against LSU at that position. When senior quarterback Casey Pachall was sidelined with a broken non-passing arm in mid-September, Boykin made six starts at quarterback.
Joeckel spent the past four years at Texas A&M, where he backed up Johnny Manziel for the past two seasons. He played the final nine minutes on Saturday, throwing one touchdown and one interception.
Samford scored on a 2-yard touchdown run by Denzel Williams late in first half and a 55-yard interception return by Jamerson Blount with five minutes to play.
TCU piled up 555 total yards, including 200 by eight different rushers, while holding Samford to 143.
"That all comes down to practice," Frogs linebacker Marcus Mallet said, "knowing what habits and tendencies your guys on your first team and second team know what they're going to do."
Samford defensive coordinator Bill D'Ottavio served as head coach in the absence of Pat Sullivan, who didn't travel while recovering from neck surgery.
"We could have played a little sharper in a lot of areas," D'Ottavio said. "Anytime you step up in this type of an arena and play this kind of football team, it challenges you. We played a lot of young kids, which was good. We're going to get experience and go forward."
TCU, coming off its first losing season since 2004, scored touchdowns on two of its first three possessions on a 2-yard run by B.J. Catalon and Listenbee's 38-yard catch.
Listenbee raced down the left sideline and beat James Bradberry in one-on-one coverage midway through the first quarter, diving for the ball near the goal line.
The touchdown pass to Porter immediately followed a TCU interception deep in Bulldogs territory. Ranthony Texada grabbed the ball in front of Gavin Sinclair near the right sideline, but the ball popped loose when Texada was hit. Paul Dawson caught it in midair and was tackled at the Samford 19.
TCU added fourth-quarter touchdowns on a 7-yard run by Trevorris Johnson and a 2-yard pass to Listenbee from backup quarterback Matt Joeckel.
Listenbee finished the game with three catches for 76 yards and two touchdowns.
Samford put together a 10-play, 75-yard drive capped by Williams running around right end for a touchdown with 3:30 remaining in the half. More than half of the Bulldogs' 143 total yards came on that possession.
Sullivan was TCU's head coach 1992-97, and his '94 team won a share of the Southwest Conference championship. That team was honored at halftime, with about 50 players in attendance along with Sullivan's wife, Jean, and other family members.
Bulldogs safety Jaquiski Tartt was frustrated that Samford didn't fare better against an FBS opponent, having played run-oriented Arkansas tight into the fourth quarter last season before losing 31-21.
"They got us with the tempo a little bit," Tartt said. "We've just to come out and play our ballgame. We didn't do that."
