'Holmes has done nothing and seems expendable even with the Bills’ mostly-anonymous receiving corps. Davis wouldn’t necessarily be missed with Eddie Yarbrough, waived last year by Denver, having impressed since training camp began. And if Mike Tolbert, the 31-year-old 5-foot-9, 250-pound veteran, was moved to fullback, the Bills might be willing to part with DiMarco. Ducasse, though, has been battling John Miller for the starting right guard job.'
