1. Injuries/another DL collapse/multiple players on the Chiefs come up big in the playoffs every year whereas only Josh really did for the Bills
2. Get BAL down by 10 in the playoffs and they lose their minds
3. Shanahan stinks in big games, Purdy sorta turned into a pumpkin, and as is the case for seemingly every opponent against KC in the playoffs, they had terrible injury and fumble luck. Greenway tore his Achilles just trying to run onto the field and KC basically got a free 7 points off a muffed punt
