Jets cornerback Darrelle Revis is prepared to sit out the start of training camp, which begins on Aug. 1, if he doesn't have a new contract by then. Sources told the New York Daily News of the development. Revis has been looking for a new deal, the richest for a cornerback, since the season ended. Revis will hold out beyond Aug. 10 and risk losing an accrued year toward free agency if there's no new deal, according to sources.
