Detroit Lions running back Reggie Bush says his role will be similar to the one he had in New Orleans and not much like his job description was with the Miami Dolphins.

The Lions plan to put Bush in the backfield and out wide at receiver, trying to take advantage of his speed. Detroit hope Bush becomes the big-play running back it hasn't had since concussions took Jahvid Best off the field.

Bush signed a $16 million, four-year contract with the Lions in March. Bush says he could've re-signed in Miami or played for Arizona, Seattle or Atlanta.

He has run for 4,162 yards and 29 touchdowns and caught 372 passes for 2,730 yards and 15 scores in two seasons in Miami and five years with the Saints.
