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.

Ceiling · 3.6

Career reserve (Reserve) — limited opportunity caps the ceiling; close to ceiling (+0.1).

Floor · 3.0

Some college production — moderate floor; downside −0.5.

Pedigree

No composite recruiting rank on file.
