IMHO - seems to me that KC has enjoyed a pretty "lucky" season and the Bills situation enhances their chances. KC has benefitted from a weaker-than-expected division, some lucky wins and a fairly "healthy" team this entire season. Our Bills on the other hand have had to endure a number of curve balls including key injuries to specific position groups, mishaps at the worst time (ex. Viking's loss), a disrupted schedule (including a home game in Detroit) and now last night's horrific injury. I don't think any team has had to deal with as much adversity as our Bills, while the Chiefs have and will continue to benefit from being luck (including home field advantage now).
