Five unbeaten NFL teams played Sunday. Only two picked up wins. The Bills, Buccaneers and Chiefs all fell in Week 3, losing their three games by a combined seven points. Each loss was meaningful. Winning saved the Colts' season, put the Dolphins in the catbird seat in the AFC East and claimed what might be a crucial tiebreaker for the Packers in the NFC playoff picture down the line.
The three losing teams will be fine in the big picture, but these were the first signs of weakness for teams that had won their first six games by a combined score of 182-75.
