The whereabouts of Saints running back Reggie Bush will be the top priority for every Colts defender in their game against the Saints on Thursday night. The multi-skilled runner is the wild card in the Saints' offense, Colts Coach Tony Dungy said. "He's like Barry Sanders," Dungy said, "but he's more involved in the passing game, and he's in more positions and more places. "Probably (former Colts and Rams back) Marshall (Faulk) is the best comparison of a guy who can catch the ball, hurt you in the passing game as well as running," he said. "He runs reverses and catches screens and catches the ball out of the backfield and lines up as a wide receiver. It's very similar to playing against Marshall."
