What happened: The TCU transfer arrives with 9,629 passing yards and 71 touchdowns across four seasons. Curt Cignetti has called Hoover a natural passer with an innate feel for the position.
Why it matters: Indiana enters 2026 after a 16-0 national championship season. Mendoza won the Heisman Trophy before becoming the No. 1 NFL draft pick.
By the numbers: Hoover has completed 65.2% of his career passes. His 42 turnovers include 33 interceptions, leaving nine other giveaways; his 71-to-33 touchdown-to-interception ratio is 2.15-to-1.
What to watch: Indiana opens Sept. 5 against North Texas. Hoover's ball security will be the early measure of his transition.
