I’ll add that the Chiefs have yet to face true adversity as their top 7 players have been relatively healthy (Mahomes, Kelce, Jones, Gay, Bolton, Thuney, Humphrey). Any game KC may see one of these players go down which could severely limit their outlook.
The Bills have (Allen, Diggs, Hyde, Poyer, Miller, Morse). Of which only Allen & Diggs have stayed healthy enough to play every game. Add in Milano & Edmunds both of whom lost games to injury. We have been more challenged on the injury front, testing our depth and grit.
