Dolphins add Michel

The Dolphins are signing RB Sony Michel to a 1-year, $2.1 million deal, ESPN reports. We don't know the guaranteed portion of that contract yet, but the overall money looks nearly identical to what the team gave Raheem Mostert back in March. The 2 veterans appear headed for a summer battle to see he pairs with Chase Edmonds atop the depth chart. Mostert's recovery from the chipped knee cartilage of last season could factor in. But Miami guaranteed $1 million on the 30-year-old's contract, so the team appears to believe he'll be fine.
