Lions defense dominates Dolphins in joint practices

Detroit's defense overwhelmed Miami's offense on day one of joint practices, even with the Dolphins missing their top receivers.

Lions defense smothers Dolphins in joint practices

Detroit’s defense controlled Day 1 of joint practices with the Dolphins, stifling Miami’s offense from start to finish. The Dolphins were without Tyreek Hill and Jaylen Waddle for much of the session, a factor that colored the pace and outcomes, but the Lions still showed depth and discipline across a full slate of drills.

Starting corners D.J. Reed and Rock Ya-Sin held steady, with injuries and personnel shuffles opening opportunities for backups to push for roles. The Lions emphasized young players with first-team opportunities, and Isaac Ukwu drew praise from coach Dan Campbell after standout preseason shows. The day featured tight one-on-one battles, swarming 7-on-7s, and a rough run of 11-on-11s that consistently favored Detroit, culminating in a red zone session where Miami managed no touchdowns against the top unit.

The takeaway is less about a single-play dominance and more about a roster blueprint taking shape. Detroit appears to be building a flexible, resilient depth chart that can sustain pressure when key players sit. The Dolphins’ missing receivers complicate a pure read on their offense, but the Lions’ alignment and communication were clear strengths in both pass defense and run fits. If this level of execution holds, Detroit could convert defensive wins in camp into on-field consistency in the regular season, punishing teams that rely on big-play moments rather than sustained drives.

For Miami, the exercise raises questions about how the offense will operate without Hill and Waddle against top-level defenses. Progress from the depth players will matter just as much as the performance of the starters, and the next few practices will test whether the Dolphins can protect the quarterback and create separation under pressure. The underlying tension is whether Detroit’s scheme can adapt to faster and more varied NFL offenses as competition intensifies.
