Chiefs, Saints stay undefeated
With all five unbeatens playing on the road, most figured we wouldn't see a handful of 5-0 teams at the end of the day. And so it came true, as the New England Patriots lost 13-6 at the Cincinnati Bengals, and the Seattle Seahawks fell 34-28 at the Indianapolis Colts. But three unblemished teams did keep their perfect records, with the New Orleans Saints -- they of an 0-4 start a season ago -- beating the Chicago Bears 26-18, the Kansas City Chiefs -- they of a 2-14 record in 2012 -- topping the Tennessee Titans 26-17, and the Denver Broncos winning close late (more on that here). What to make of it all?
