Patriots Add Hawaii Safety Peter Manuma on Undrafted Deal

The Patriots signed undrafted safety Peter Manuma to their 90-man roster on May 11, per the Boston Herald, adding another late-stage prospect from their rookie minicamp tryout window. Manuma, a four-year starter at Hawaii, recorded five interceptions during his college career—a respectable ball-hawking resume for an undrafted prospect, but one that arrived without NFL draft capital for a reason.

This move is part of New England's broader post-draft depth-building exercise. Manuma's signing adds to the secondary depth chart ahead of training camp, but the Patriots' safety room already has established veterans and higher-pedigreed prospects ahead of him. For a UDFA safety, particularly one from a mid-major program, the path to meaningful playing time is steep. Most undrafted secondary players either develop into special-teams contributors or cycle through camp and preseason without sticking on the 53-man roster.

From a roster-construction standpoint, the Patriots are threading together depth depth across the board—a sensible approach for a franchise in rebuild mode. But from a predictive standpoint, signing a single UDFA safety has zero impact on team defensive metrics or secondary coverage efficiency. Manuma's five college interceptions don't project forward to the NFL; UDFA safeties rarely earn the snap count to influence team interception totals or pass-defense prop lines.

Bettors tracking Patriots season-long defensive props—team sacks, opponent passing yards allowed, secondary interception output—should ignore this news entirely. Manuma will need to win a starting role or secure consistent snaps to matter in any defensive framework, and the odds of a undrafted safety leapfrogging the depth chart before the season opens are minimal. This is roster maintenance, not a change agent.
