Really good points here @Hapless Bills Fan More than any other game football is about matchups. Given the talent on both sides of the ball on both teams, the D coordinators are going to have to draw up coverage schemes to take away what the other team does best. For Bills, it's Diggs and Beasley. For KC it's Kelce and Hill. The coverage and depth of each team's defensive backfield will determine the winner. Personally I believe the Bills D backfield > KC's and will limit the KC offense to 3 TDs.
The Bills need to get to 4 TDs to win on SUN. The RBs, Josh and Knox need to come up with 2 of those TDs.
