Kansas City Chiefs fall to Buffalo Bills in a statement loss that exposed critical weaknesses on both sides of the ball. Can Andy Reid and Steve Spagnuolo fix these issues before a potential playoff rematch? Ryan Tracy and Matt Derrick from ChiefsDigest.com break down how Buffalo's defense elevated their game against Patrick Mahomes, holding the Chiefs to just 3 of 13 on third downs. The analysis covers James Cook's 100-yard rushing performance, the controversial goal-line stand that kept Kansas City out of the end zone, and the intentional grounding call that shifted momentum. Despite the loss, bright spots emerged from Kingsley Suamataia's breakout performance at left guard, Trent McDuffie's lockdown coverage, and Hollywood Brown's continued development. The discussion examines Josh Allen's near-perfect passing efficiency, offensive line protection failures, and why the Chiefs abandoned their aggressive play-calling philosophy.
