Miami's cornerback overhaul has flipped a preseason weakness into a real strength. Jack Jones, Rasul Douglas and Cornell Armstrong have formed a productive trio after a wave of late-signings and practice-squad moves. Jones's goal-line fumble? stripped away by design, a symbol of a unit that finally respects its roles.

Despite a 122.9 passer rating allowed, the group is buoyed by a veteran presence (Douglas) and a red-hot playmaker (Jones). With a matchup at Carolina on deck, fantasy bettors should note the sustained turnover-creating defense and the potential for continued nickel versatility from Armstrong as Kohou recovers.

Miami's right side is in flux as Austin Jackson lands on IR and James Daniels joins him, forcing a reshaped O-line for at least four games. Borom steps in at right tackle with Kion Smith sliding to right guard; Strange, Brunskill or Lamm may inherit later opportunities. Waller remains in the lineup with a two-TE look, and Wilson Jr. plus Patterson get practice-squad elevations to stay ready. Cornell Armstrong moves up to fifth cornerback as Bonner sits, while Wright is doubtful and Waller stays active.

Depth and tempo become the x-factors: the Dolphins will lean on internal depth, situational protection schemes, and occasional run-game adjustments against a brutal early schedule (Patriots, Bills, Jets, Panthers). The earliest Jackson or Daniels could return is Week 6 vs Chargers, giving Miami a light at the end of the tunnel as Eichenberg works off PUP. Fantasy angles hinge on who seizes the opportunistic reps along the line and how the TE and RB options are deployed in the shift.
