We know the Chiefs aren't the type of team that can put up three fourth quarter touchdowns in a comeback. They need to play with the lead, or close to the lead. It's not a coincidence that the Chiefs began to fall apart last week against the Atlanta Falcons once they took a two-score lead.
For whatever reason, the Chiefs are not a come-from-behind team.
So that means one of if not the biggest key to the game is starting fast. KC needs to put points on the board in the first half. They need to keep the game within a score. They can not get down 10-0 in the first quarter and even if they do get down that much that early they need to stick to the game plan, which likely includes lots of Jamaal Charles and Peyton Hillis.
Running the ball, playing good defense, avoiding special teams errors....all important. But none of it will matter if KC doesn't start fast.
