'This is a hand-signed official NFL football signed by Redskins running back Clinton Portis. The football is an official ball identical to the one used in NFL games. Portis was traded to the Redskins in one of the offseason's biggest transactions and will serve as the offensive centerpiece for legendary coach Joe Gibbs. Portis, 22, has great speed, elusiveness and field vision, which enables him to dodge tacklers and break through holes in the line of scrimmage.'
