Miami Dolphins' 2025 roster battles hinge on three up-front spots: tight end, interior defensive line, and the ninth offensive line slot. Waller's training-camp debut is delayed, so Tanner Conner leads the inline TE push while Pharaoh Brown and Julian Hill chase the primary in-line role. Ingold's injury opens more chances for Conner’s versatility, including fullback duties in certain packages. Zeek Biggers emerges as a stock-up option at DT, leveraging length and a developing pad level to push for a spot in a deep interior line group. Andrew Meyer and Jonah Savaiinaea sit among the hot names to backfill depth, with Kion Smith losing traction after a tough Chicago outing. The Dolphins face a Bears tune-up and two Detroit joint practices that will help sort the 53-man roster.

On the trenches, Miami could keep eight or nine linemen this season, depending on health and growth. Meyer’s camp ascent and Conner’s TE flexibility could be decisive in the final cuts, especially if Waller’s return slips. The Detroit sessions highlight Biggers’ potential impact on the inside, while Brunskill remains a veteran fallback option for the ninth OL spot. Overall, the emphasis remains on versatile pieces who can fill multiple roles and adapt quickly as the season unfolds.

For fantasy players, the smart play is to monitor Waller’s debut timing, Conner’s usage in inline and move roles, and Biggers’ early snaps for a hint of an upshot in interior rushes. If Waller sits longer, Conner could command more targets in the short term, with Brown offering red-zone flashes. Meyer and Savaiinaea are long-shot depth pieces whose eventual roles could tilt late-season rosters.
