How did the Chiefs stifle the Packers' passing game? Mostly with extra coverage and a standard four-man pass rush. According to ESPN Stats & Information, the Chiefs used at least five defensive backs on 86 percent of the Packers' plays Sunday. On top of that, they sent four or less pass rushers on 78.6 of Rodgers' dropbacks. As a result, Rodgers completed only two of 12 passes downfield, defined as 15 or more yards past the line of scrimmage -- the worst completion percentage on such throws all year. The Packers had four dropped passes, but Rodgers also had a tough time getting the ball into the small windows afforded by Chiefs coverage. He either underthrew or overthrew 10 of his 35 passes. Say what you will about the drops and Greg Jennings' absence, but on a relative scale there is no doubt Rodgers played the worst game of his season
