Keaton Mennen brings size, runway, and developmental upside to South Dakota’s defensive front
Mennen is a 2026 South Dakota defensive lineman from Van Meter, Iowa, listed at 6-foot-5, 270 pounds, and his appeal starts with that long, powerful frame built for trench work. He was a committed in-state recruit before flipping to Iowa State, then later ended up back in the Coyotes’ mix, which says he has real program-fit value and regional traction. For South Dakota, he projects as a high-ceiling interior/edge disruptor: big enough to absorb blocks, athletic enough to keep developing, and the kind of freshman DL who can become a nuisance if coached up right.
