Cardinals rookie running back Chris "Beanie" Wells has lost 18 pounds since he began working out with conditioning coach John Lott. Wells weighed 247 pounds when he began working with Lott, and the trainer estimates that the running back's playing weight will be about 225 pounds. "I made a promise to (Larry) Fitzgerald, a promise to Kenny (Whisenhunt), a promise to players interested," Lott said of his interest in seeing Beanie break out. "I think this kid has a chance to do something. He's got the tools. ... He could be a beast."
