Tiki Barber put the ultimate exclamation point on the Giants' season of turmoil with a franchise-rushing record, a dominating performance that virtually assures his career will last at least one more week. In his last regular-season game, Barber carried 23 times for 234 yards and three touchdowns Saturday night in a 34-28 victory over Washington. The win ends New York's seven-week free fall just in time for the Giants to make the postseason as a .500 team.
