Dolphins Add Fullback Depth With DJ Herman Signing

The Dolphins signed fullback DJ Herman on Monday, addressing an immediate gap in their backfield depth chart. Herman, an undrafted prospect from San Diego State, participated in Miami's rookie minicamp on a tryout basis before earning a roster spot. The move is straightforward roster management—Miami currently carries no other fullbacks on the active roster, making Herman's acquisition less about immediate impact and more about filling a structural need.

Herman's college profile suggests a versatile complementary piece rather than a difference-maker. He played linebacker at San Diego State, appearing in 49 games with 56 tackles and a tackle for loss. His path to the NFL hinges almost entirely on special teams contribution, where he logged significant snaps in his college tenure. The signing reflects Miami's willingness to evaluate unconventional positional crossovers, though Herman will need to prove he can operate effectively in a crowded training camp environment.

From a roster construction standpoint, fullbacks carry minimal leverage on Vegas totals or individual player prop markets. Herman's presence doesn't alter Miami's offensive ceiling or reshape their run-game architecture in any meaningful way. The Dolphins' ground-game efficiency depends far more on their primary running backs and offensive line continuity than on a transitional fullback prospect.

That said, Herman's signing is a non-event for bettors. Undrafted fullbacks rarely see enough snaps to move volume props, and Miami's team totals or spread pricing won't budge based on his roster addition. What matters for prop bettors tracking the Dolphins offense remains the health and usage of their established skill-position players and whether the team's passing attack maintains efficiency relative to season projections. Herman's roster inclusion is administrative depth; it has no bearing on meaningful betting markets.
