The KC game was at KC and they had the Giants @ NY until 3 minutes left in the game. So, you dont think the Bills were trying to win? Your talking about a team that beat NE and was still playing for the division last week. KC was in 1st place with Matt Cassel at the helm when they got stamped out "in KC". Your logic is flawed. Can Dallas win by 14? Absolutely, but that team is like betting Notre Dame. People bet Dallas just for fun. Especially in this spot I expect a let down.
