ALLEN PARK, Mich. (AP) - Running back Reggie Bush was one of the bigger free-agent signings in Detroit Lions history. That doesn't mean he'll be hogging the carries this season. Joique Bell and Mikel Leshoure rushed for more than a combined 1,000 yards in Detroit's pass-happy offense last year and offensive coordinator Scott Linehan thinks there's still room for both of them. Bush made his biggest impact as a receiver and returner after New Orleans drafted him in the first round of the 2006 draft. He showed he could be an everyday running back after he went to Miami before the 2011 season.
