Without a doubt, the biggest storyline from Texas Tech's crucial 34-26 victory over No. 22 Arizona in Lubbock was the insertion of Thomas Castellanos into the offense as the new starting quarterback. It was a move that many Red Raider fans felt was necessary given Will Hammond's struggles against Cincinnati a week ago, and it may salvage the 2026 season.
Castellanos was solid in his first full-game action for Texas Tech. He accounted for 261 yards of total offense and three touchdowns (two through the air).
Though his performance didn't set any records, it did revitalize an offense that has been sputtering for most of the season. After the game, Castellanos admitted that he wasn't at his best against the Wildcats, especially when throwing the ball.
"Just getting the feeling to go out there today and kind of settle in," he said, "you know, I'm still rusty. I've still got a lot to work on. We have really good receivers, and I overshot those guys a lot today, but just more time with them, more chemistry, I think we'll get it down."
Through the air, Castellanos was only serviceable. He was 11-for-24 passing for 144 yards. However, he had two beautiful touchdown passes from outside the red zone that helped turn the tide for his team, as both gave the Red Raiders the lead when they were trailing.
Perhaps the most important element he provided, though, was confidence. He was decisive with his throws, and even the ones he missed were assertive enough to force the defense to respect his willingness to challenge the secondary deep.
As a result, Arizona couldn't crowd the line of scrimmage to stop the run. The result was a 328-yard rushing day from the Red Raiders, 117 of which came via Castellanos' legs.
"He gave us juice today," head coach Joey McGuire said. "There was great leadership from him. He plays with a confidence, he's played a lot of football. I thought you saw a very experienced quarterback out there today, and you know, he made some really good plays. I thought he played really well, and we just got to build on it."
Of course, Castellanos will have to be better when throwing the ball in upcoming games. Now that there is a full game of footage with him as Tech's QB1, opposing defenses will have a better idea of how to gameplan to force him to make plays from the pocket.
This isn't the 90s when a player like former Red Raider QB Zebby Lethridge could lead a team all season by being essentially an extension of the running game. Though Castellanos' ability to carry the ball gives the offense a larger margin for error, the passing game needs to come around for Tech to win the Big 12.
"We're going to complete some of those," McGuire said. "Kenny [Johnson] was really close to one. There were two to him that were really close. Tommy's got a really big arm. I think one thing, without a doubt, he was juiced up today, like, he was juiced up all week. I mean, he was really bouncing around, you know, the opportunity."
Castellanos has been in an odd situation all season. He didn't join the program until just days before the first game. Then, he spent most of the season primarily working on red-zone packages.
What's more, in the middle of the year, he was sidelined for two weeks when a Kentucky court temporarily took away the fifth-year senior's eligibility. As a result, he's had far less time to work with Tech's starting pass catchers than one would like. Hopefully, Castellanos and his receivers will gel quickly now that he will get the first-team reps moving forward.
In all, though, it was a promising start from the new starting QB. Facing a quality opponent in a game his team couldn't afford to lose, he elevated the offense with his play and with his confidence. Even if he was a little rusty, he proved that he is a gamer. Now, the 2026 season is in his hands.
