From The Athletic:

“I think BYU probably has more team speed (on defense [than Iowa State]),” the veteran coach said, adding that he thought highly of some of the Cougars’ front-seven talent. “(Tyler Batty and Blake Mangelson) are both really long and athletic, and (linebacker Jack Kelly) runs well, has good closing speed and plays really hard. You watch them on film and on some of the highlight packages they put out, you can just see that they have great energy and a lot of juice. It’s sincere and raw, how they’re playing for each other. It’s impressive.”

Another Big 12 defensive coordinator said he sees a BYU team that is playing with a ton of confidence. “(Jake Retzlaff) has a really strong arm and is playing with a lot confidence. They mask the offensive line by max-protecting. He’ll trust his receivers and throw it up there, but that’s why he has the picks that he has. He still makes some bad judgment throws.”
