What It Means:

Raheem Mostert appeared to have the Dolphins' backfield to himself after Chase Edmonds was shipped off to the Denver Broncos, but then Wilson was reunited with former 49ers offensive coordinator Mike McDaniel. Mostert will presumably remain the starter for now, but Wilson's arrival might lead the Dolphins to go with more of a committee backfield. Either way, Myles Gaskin and Salvon Ahmed will move down the depth chart. Tyrion Davis-Price and Jordan Mason will compete to replace Wilson as Christian McCaffrey's primary backup in San Francisco, at least until Elijah Mitchell (knee) returns.

Wilson averaged 13.1 opportunities per game and a career-high 5.1 yards per carry for the Dolphins this season. Among the 50 running backs with at least 40 carries on the year, Wilson is 33rd (negative-0.01) and Mostert is 31st (0.00) in Rushing Net Expected Points per carry.
