Detroit Lions coach Jim Schwartz hopes to revitalize the career of Reggie Bush this season.

As a result, Lions running backs Mikel Leshoure and Joique Bell will likely see their roles redefined.

Leshoure started in 14 games last season during the absence of Jahvid Best. He had 798 rushing yards and nine touchdowns, plus 214 receiving yards.

Bell appeared in 16 games and eventually replaced Kevin Smith on Detroit's active roster. He finished with 414 rushing yards and three touchdowns, plus 485 receiving yards.

Both will likely have to fight for playing time behind Bush in 2013.

Even though Bell and Leshoure will probably see a reduction of playing time, Schwartz said there will be plenty of touches for all three running backs in 2013.

"We have 1,000 offensive plays," Schwartz said. "There's 1,000 touches in our offense every year. There's more than enough for everybody to get the football, and you're going to need it. There (are) teams that have five wide receivers. Look at Green Bay last year. They lost (Greg) Jennings for a good stretch of time. They also lost Jordy Nelson for a game or two with a hamstring, but they were able to keep grinding because they have all those guys. New Orleans has a big stable of running backs. They had guys that were inactive, but eventually you're going to need them, and when they are (active), they will be able to go in and make plays.
