I remember Chiefs shut Cook down in mid-Nov game and Bills only got to 103 total rushing yards on Josh's TD run for the last TD.
The Chiefs have struggled versus the run since late NOV game vs Raiders up through Houston Playoff game. In their last 6 games (not counting last regular season game of KC backups vs Broncos) the Chiefs have given up 5.33 ypc on 147 opponent rushes for 784 yards. The Raiders, Browns, Steelers and Texans all put up big yards rushing on the Chiefs. In 2 games, including their playoff game, the Texans put up 233 Yards total on 46 carries for a 5 Yd Average.
The Bills hardly used their 6 man rotation in 1st game vs Chiefs as the higher usage rate came after their week 12 bye. The Bills will run on KC and that will cause stress on their coverage if Brady uses Play Action out of the Jumbo formation. The TEs and RBs should be open.
