ANALYSISMattison is swapping teams with fellow running back
Raheem Mostert, who agreed to a deal with Las Vegas earlier Thursday. While Mostert perhaps has a chance to rebound from a disappointing 2024 and earn a key role, Mattison will merely be competing for a backup job behind
De'Von Achane. The Dolphins presumably hope 2024 fourth-round pick
Jaylen Wright secures the second spot on the depth chart, with Mattison essentially being a backup plan for the backup. It's a tough situation for earning playing time, albeit with the outside chance of a handsome payoff if injuries eventually thrust Mattison into a starting role in head coach Mike McDaniel's offense.
