Colts get passing grades on tough opening
INDIANAPOLIS -- The NFL schedule-makers sent Indianapolis an early message. Play well in the opening month, and it could lead to a better finish. Four weeks into the season, the Colts have done their part. They are 3-1 and hold a distinct advantage in the AFC South after wins at Tennessee and Jacksonville. But the players understand there's still more to do. "I don't really know what we've done yet," quarterback Peyton Manning said. "We're 3-1, but that means absolutely nothing now." Manning, last year's co-MVP, called the opening obstacle course the most challenging start of his seven-year NFL career.
