Lions face roster tests in preseason

The Lions lost to the Dolphins, but several players showed they belong in the roster battles ahead of Week 1.

7 winners, 3 losers from the Lions’ preseason loss to the Dolphins

The Detroit Lions fell to the Miami Dolphins in a preseason game that still offered a balanced view of where the roster stands. Isaac TeSlaa stood out with four catches for 41 yards and a red zone touchdown, signaling that the rookie could push for quick impact. Jackson Meeks followed with seven catches for 93 yards and a touchdown, highlighting the push for WR6 and the value of a versatile receiver who can contribute in multiple roles.
Kyle Allen continued to prove the backup quarterback battle is worth watching, finishing 14 of 17 for 124 yards with two scores and clean pocket work in the first half. Erik Hallett was the defensive standout, breaking up passes and showing the versatility to play safety or corner. Chris Smith and Brodric Martin anchored the interior line, helping limit the Dolphins early rushing lanes. Sione Vaki added a rushing score and showed value on special teams, a reminder that roster spots can hinge on multi tool players.
On the negative side, Jamarco Jones had a rough day at left tackle, and Loren Strickland’s role at safety didn to be overtaken by Ian Kennelly and Hallett as the depth chart takes shape. The Lions also piled up 13 penalties for 86 yards, a figure that thins the margin for error once the regular season arrives. These outcomes underline that the final 53 will hinge on both performance and discipline all around the roster.

This game underscored how quickly a preseason performance can shift discussions around the roster. TeSlaa and Meeks are not just filling spots; they are forcing conversations about WR3 and WR6 depth, especially if chemistry with the starting quarterback continues to grow. The QB room appears to be tightening around Allen, whose poise and accuracy keep him in the driver's seat for the backup role, while Hooker will have to show more than flashes in the next outing.
Defensively, Hallett’s move toward cornerback depth and his playmaking is a reminder that the Lions value flexible defensive backs who can cover multiple roles. Smith and Martin’s interior work matters because stopping the run early creates easier paths for blitzes and plays on passing downs. Penalties loom as a different kind of threat; a line of scrimmage discipline and formational precision will need to improve if the team wants to avoid giving spare yards to opponents in real games.
Overall, the Lions are sorting through a deep pool of talent. The question now is how many of these preseason performances translate into reliable depth on Sunday and whether the coaching staff trusts youth in high leverage areas or leans toward veterans for stability.
