Scouting Verdict
Mason Rivera is a senior who was a heavy producer at FCS Cal Poly (74 tackles, 5 PD, INT, FF in 2025) but arrives at UCLA projected as a Reserve. The production is loud but the level (FCS) and depth-chart status keep this at longshot grade — a classic stat-padder-at-low-level read.
