Freshman Caleb Williams dazzled in his first start for Oklahoma on Saturday, throwing four touchdown passes and running for another as the No. 4 Sooners beat visiting TCU 52-31.

Williams became the first true freshman to start at quarterback for Oklahoma since Cale Gundy (a Sooners assistant since 1999 and OU's current co-offensive coordinator) in 1990. Williams completed his first 10 passes against the Horned Frogs, with his first incompletion coming on a dropped pass in the end zone by Austin Stogner with about 12 minutes left in the second quarter.

He ended the night going 18-of-23 for 295 yards and added another 66 yards rushing, including a 41-yard touchdown run in the third quarter. The Sooners had 525 yards of offense on just 58 snaps, an average of 9.1 yards per play, and drew three pass interference penalties on long pass attempts that might have otherwise gone for big gains.

While Sooners coach Lincoln Riley said after the game that he decided on making switch from Spencer Rattler to Williams midweek, the public announcement was made about 15 minutes before kickoff. An enthusiastic Oklahoma crowd, which had chanted, "We want Caleb," at the last home game -- a 16-13 win over West Virginia -- cheered wildly when Williams was announced with the starting lineup.

The decision ended speculation after initial questions about who might be the starter. The OU Daily, the student newspaper, reported Tuesday that Williams took the majority of the first-team reps in practice based on a vantage point from a public building on campus, prompting Oklahoma to cancel all media availability for the remainder of the week.

"I think both those guys handled the week extremely well, considering all the circumstances," Riley said, adding that it felt mostly like a "normal week."

Rattler, the preseason Heisman Trophy favorite, was benched after two turnovers early in the Sooners' game last week against Texas. Williams came off the bench with Oklahoma trailing 35-17 to ignite a furious comeback in the Sooners' 55-48 win.

As a redshirt freshman last season, Rattler threw for 3,031 yards with 28 touchdowns and seven interceptions -- including just three of those over his final seven games -- and completed 47 passes of 20 or more yards, which ranked ninth nationally.

This season, Rattler has thrown for 1,371 yards with 10 touchdowns and five interceptions as the Sooners offense struggled. Rattler's 71.9 QBR ranks 30th nationally.

Williams, from Washington, D.C., was the No. 1 dual-threat quarterback and No. 16 overall prospect in the 2021 ESPN 300. Rattler was the No. 1 dual-threat prospect in the 2019 class.

Riley has defended Rattler, saying the offense's struggles aren't completely on him. Riley said Saturday night he would have had no problems playing Rattler.

"Caleb got the opportunity tonight and played well," Riley said. "I'm confident had Spencer got the opportunity tonight, the way he practiced, he would've played well tonight too."

Redshirt sophomore receiver Jadon Haselwood, who had three career touchdowns at Oklahoma until catching three on Saturday night from Williams, said the freshman quarterback was unflappable.

"I don't think he ever feels pressure," Haselwood said. "He felt no pressure, no fear. He can sling it and get the ball downfield."
