That fumble was huge and really kept KC close. Philly was dominating the 1st half, but was only up by 10 pts, felt like it was a lot more. Instead of being up 10 at the half, they could have been up 17, or more by 20 or 24 if they scored on that drive instead of turning it over. Considering that KC scored on every drive in the 2nd half, there probably wouldn't have been enough time to to come back from 20 or 24. The Philly defense could still have played as poorly as they did in the 2nd half and still won the game.
