Mike Bell was so impressive in Saturday's preseason game that the Saints now appear eager to use a three running back rotation. Bell had 10 carries for 100 yards and will likely join Pierre Thomas and Reggie Bush in receiving carries. "I think so," Saints Coach Sean Payton said Wednesday when asked if the club might employ a three-back rotation this season. The Raiders run Justin Fargas, Darren McFadden and Michael Bush with equal confidence. "A lot of people do (it)," Payton said. "You play a long season, and I've just been taught that that's a position you need to stack it up and have depth, because you know you're going to have some nicks along the way. The exception to the rule is the team that can feature one back the whole season."
