L.J. Shelton will start for the Miami Dolphins at right tackle, and Ronnie Brown will be the starting running back when the team opens its season Sunday on the road against the Washington Redskins. "Personnel-wise, who's going to start the game . . . there could be two running backs out there, but Ronnie will be our starting tailback," Dolphins coach Cam Cameron said Wednesday. "I think he earned the job."
