AMES, Iowa (AP) — Iowa State looked relatively set at defensive line at the end of last season. It all fell apart in the offseason. Nose guard Brandon Jensen quit the team with a year of eligibility left, and starting tackle Rodney Coe was dismissed for violating team rules. Fellow tackle David Irving was kicked off the team after photos of him holding an uprooted stop sign in the midst of a campus-wide disturbance emerged on social media.
