The Kansas City Chiefs defense was not very well behaved in 2017. In fact, they had the sixth-worst yards-per-play defense in the NFL last season.
I wrote an article earlier this offseason that took a look at the Chiefs defensive talent in 2017, and the results were not pretty.
In a sampling of nine teams, the Chiefs defensive personnel was by far the least talented group. It’s almost amazing to me defensive coordinator Bob Sutton and the Chiefs were able to finish near the middle of the NFL in points per game allowed (Seriously, they should be thanking Alex Smith for taking care of the ball so well).
