Arguably the season's biggest story is the improved play of the Kansas City Chiefs defense. Through six weeks, it’s proven to be elite. Through six weeks, the Chiefs rank sixth in expected points added (EPA) and success rate on defense. Even while playing tough offenses like the Detroit Lions, Jacksonville Jaguars and Minnesota Vikings, the defense has proven capable every week.
There are many reasons for this. Defensive tackle Chris Jones is playing great. Cornerbacks L'Jarius Sneed and Trent McDuffie have blanketed top wide receivers every week. The addition of linebacker Drue Tranquill, along with internal development at the position, has led to some of the best linebacker play the Chiefs have enjoyed in years.
