As he prepares for his fourth NFL season, Saints running back Reggie Bush is under the impression that the organization wants to make him the focus of the running game. “They’re looking for me to be the guy back there,” Bush said Sunday, according to the Associated Press. “By the moves that they’re making, it definitely speaks volumes to me as to what I need to prepare myself for,” he added. Um, what moves? The long-expected release of Deuce McAllister? It means nothing, in our view, in relation to Bush’s career. Instead, the move signifies that, until further notice, Pierre Thomas will be the primary inside guy, and that Bush will continue to be a glorified third-down back. Why else would the Saints have been linked to LaDainian Tomlinson? And why else would so many people be linking the Saints’ first-round draft pick to Georgia’s Knowshown Moreno? Bush has had ample opportunity to become “the guy.” Running backs don’t simply become “the guy” after three full NFL seasons, especially with a knee that gradually is deteriorating. If a first-round running back is going to be “the guy,” he becomes “the guy” right away. Like Adrian Peterson. So Bush would be wise to understand his role -- and to remember that his career rushing average is 3.7 yards per carry.
