5. Conservative party in Kansas City: Chiefs coach Todd Haley and his talented staff are showing a conservative approach can work in his pass-happy league. The Chiefs lead the AFC West with a 4-2 record built on running and smart defense. The Chiefs are averaging 35.2 runs a game with an incredible 5.0-yard average. Jamaal Charles and Thomas Jones are both on pace for 1,000-yard seasons. But the surprising numbers are on defense. Chiefs defensive coordinator Romeo Crennel is playing it smart and conservatively on defense. According to ESPN Stats & Information, the Chiefs have blitzed less than any team in football. Crennel has rushed an extra defender on only 18.9 percent of the pass plays. Last year, D-coordinator Clancy Pendergast blitzed on 32.4 percent of the pass plays, but quarterbacks had a 106.2 rating against Kansas City. This year, opponents are completing only 46.3 percent of their passes against Chiefs blitzes. Crennel is stressing coverage.
