The difference in the defense was two-fold.
1) The DL did not get blown off the ball at the LOS and stopped the run on first down, plus most of the other downs.
2) The Chiefs don't have a ton of talent at WR outside of Hill's speed. Tre and Gaines did well so when we blitzed, which was often, Smith couldn't find wide open guys like Rivers did last week. And for some reason they ignored Kelce.
