12:33 AM CDT on Wednesday, May 26, 2004 Bill Parcells made a rare public appearance when the PGA Tour swung through Irving recently. In a conversation with CBS’ Jim Nantz, the master of melodrama, Parcells said he was leaning toward a running back-by-committee approach. It’s one of Parcells’ favorite terms, especially because he had success with the approach while coaching the New York Giants. Cowboys fans aren’t used to that concept, thanks to the lengthy and successful careers of Tony Dorsett and Emmitt Smith. But if the Cowboys have to actually rely on this approach, turn out the lights on another playoff run. At this point, Parcells is only providing shelter to Julius Jones, who could feel more pressure than any second-round pick in the history of the game. After all, Parcells saw something in Jones that made him pass on the top-rated running backs in the draft. And for a few days, Cowboys fans were quick with their criticism. Judging by your recent e-mails, though, Parcells has returned to “genius” status, and that extra first-round pick in 2005 doesn’t sound too bad. Here’s how Parcells’ so-called committee will work: Julius Jones on first down, Julius Jones on second down and sneak ol’ Richie Anderson in there to help out Julius on third. That leaves one burning question. With Troy Hambrick moving to browner pastures in Oakland, who will be Jones’ backup at halfback? Until further notice from Parcells, the candidates include practice squad veteran ReShard Lee, former college fullback Erik Bickerstaff and change-of-pace back (read: fragile) Aveion Cason. Cason has added 15 pounds to his 5-10, 204-pound frame, but he’s recovering from knee surgery. Parcells wouldn’t dream of using him for more than four or five carries per game. Bickerstaff, who had one carry during his stay at Wisconsin, rushed for 56 yards on 19 carries in limited playing time late last season. Lee (5-10, 232), who played at Middle Tennessee State, showed promise during last year’s training camp. But a knee injury eventually led to his early departure. He joined the Cowboys’ practice squad late last season. The Cowboys could be in serious trouble if something happens to Jones. Fans would suddenly appreciate Hambrick’s south-and-south running style. For the last few weeks, everyone has wondered if the Cowboys will eventually try to bring in a starting cornerback. But the team might end up focusing on a veteran running back instead. Anyone seen Adrian Murrell?
