Ty Dieffenbach brings dual-threat upside and big-play flashes to Cal Poly’s QB room
In the 2025 season, Dieffenbach showed why he’s intriguing: he threw for 1,305 yards and 9 touchdowns, added 321 rushing yards and 4 scores, and earned Big Sky Offensive Player of the Week honors after a 263-yard, 3-total-TD debut for Cal Poly.[1][7][15] His value is in his size (6-foot-6), mobility, and ability to stress defenses both in structure and on scrambles, but the fit question is ball security and consistency, since he also had 9 interceptions and an up-and-down season that included injury-related disruption and rotation at quarterback.[7][9][13]
