Following the devastating season-ending injury to Alexander Mattison, the Miami Dolphins were quick to sign running backs Aaron Shampklin and Mike Boone in his place.
However, it's unlikely either makes a significant enough impact to warrant a place on Miami's 53-man roster to start the season. If that holds to be true, where will the Dolphins find their fourth RB? Will they even look for one?
Losing Mattison for the year was a big blow to this Miami backfield. Third on the depth chart, he was helping the Dolphins' offense this offseason with their short-yardage issues, which we saw from their preseason game against the Chicago Bears, remains a concern.
