The losses to STL and Arizona were road games where they were underdogs. The Tampa game was a home game and so was Carolina. In both games a lot of the nose-to-nose battles went the other way (much of that was holding by TB's line O Line and Carolina's DBs, but hey, this is the fucking playoffs!). The loss to NE was a push, three-point dogs and lost by three. This obviously was a game KC should have won. I would say beating the Giants in 06 was a pretty solid win and getting to the title game against STL was also solid. So he hasn't always been favored when he won and definitely not when he lost.

Marv has never won a playoff game. We aren't talking about title games or Super Bowls, we're talking about the first round. Without looking I know at least four of those were home games which is a pretty clear indicator that they were favored.
