Scouting Verdict

Ty Dieffenbach is a Cal Poly (FCS) transfer QB with a full FCS season (1,305 yards, a poor 9-9 TD-INT, plus 321 rushing yards) but a Reserve projection at UCLA. The FCS level and rough turnover ratio keep this at longshot grade despite the live arm and mobility.

Ceiling · 3.8

Career reserve (Reserve) — limited opportunity caps the ceiling; close to ceiling (+0.4) · QB premium.

Floor · 2.4

Some college production — moderate floor; downside −1.0.
