my brain tells me (assuming we are healthy and such) that it's another multi lead change game going down to the wire, but for some reason based on what we saw on sunday night, i think a healthy bills team can win decisively vs kc, especially at home. adding back brown might be the biggest singe change maker, a few of those outside runs might get broken open and that changes everything on the drive. if you throw in a two handed cooper, coleman, and kinkaid, it bumps samuel and shakir down the ladder in terms of who covers them (or else they can leave coleman one on one on the outside w a lesser corner, but that is a dream match up for us), and gives kc fits.
also, the pass rush and coverage scheme were so effective at disrupting mahomes, who has not been good at all this season. if we are actually full power on DL w smoot and carter making contributions, and have LBs 1 and 2 (for the first time since what, the early miami game last year?) playing, i think that translates to an extra turnover or punts for kc, and might also force a FG instead of TD.
i might be overly optimistic, and be thinking that mcd will continue to coach smart when his playoff history tells us the opposite, but frankly i just don't think kc is great this season. detroit, pittz, and as a match up baltimore are way scarier. the analogy of kc vs philly last year is very apt.
