At least one of the teams isn't a major surprise, with the reigning Super Bowl champion Kansas City Chiefs starting 3-0 for the sixth time of coach Andy Reid's tenure. Others, however, are literally defying the odds.

KC held on for a 22-17 road victory over the Atlanta Falcons on Sunday night to improve to 3-0, as the defense had two dramatic stands in the fourth quarter. The Chiefs stopped the Falcons on two plays from the 5-yard line to preserve a five-point lead with four minutes left, then stopped them again on their final drive.

The Kansas City Chiefs are one of the NFL's four 3-0 teams, but it was difficult to tell in their locker room after Sunday night's 22-17 win over the Atlanta Falcons. Patrick Mahomes in particular sounded a little like the Chiefs had lost.
