Dolphins part ways with RB Reggie Bush

As expected, tailback Reggie Bush is no longer a member of the Miami Dolphins. Bush officially signed a four-year contract with the Detroit Lions Wednesday on Day 2 of free agency.

Bush rushed for more than 2,000 yards in his two years with the Dolphins. But returning to Miami was never a realistic option.

The Dolphins were ready to move on with their two younger running backs: Lamar Miller and Daniel Thomas. Miami had other needs to address in free agency and didn't feel obligated to sign a third running back to an already deep position.

This week we took a look at Miller replacing Bush in the lineup. The second-year tailback led the Dolphins with 4.9 yards per carry. Miller seems like a good fit in Miami’s quick-hitting, West Coast offense. The biggest area of concern is pass protection, and that’s something Miller needs to work on.

Detroit got a solid player in Bush. But I do not think Miami's front office is too worried Wednesday that Bush signed with another team.
