This stat on the Kansas City Chiefs pass rush says a lot about the secondary

Random interesting stat on the Kansas City Chiefs from Pro Football Focus:

Most sacks when rushing 4 or fewer defenders: 1. Bills 43 2. Eagles 38 3. Jaguars 36 4. Chiefs 35 5. Lions 34

I saw this and thought how many sacks did the Chiefs have last season? 46 sacks. That the Chiefs can get that much pressure with four defenders is a game changer. Not only is that a good pass rushing number but it also certainly contributed to the Chiefs secondary success, which didn't allow a 300-yard passer last season. The Chiefs secondary was good last year but that pass rush ... that was a hell of a pass rush.
