was it them looking good as much as it was kc looking terrible? not taking anyhing away from their win because they did play well. But kc just looked lost. dropped passes, turnovers, bad tackling... it was rough to watch.
Combination of both I think. KC looked horrible and the Bills came to play. I think the Bills could be decent on offense as Gailey is great offensive play caller and they have some players who can make some plays. The O-Line is horrible and the defense is highly suspect. KC has just looked terrible all pre-season.
