Many people already have their doubts about the legacy and value of Todd Haley as a coach, but you can’t say that he hasn’t plied his trade the hard way. He spent a decade just as a wide receivers coach for the Jets, Bears, and Cowboys before he was promoted to offensive coordinator with the Arizona Cardinals. This -- along with his prior association with then-general manager of the Kansas City Chiefs Scott Pioli -- became his leaping-off point to a head coaching job with Kansas City. Unfortunately, it was rife with controversy, as first running back Larry Johnson and then offensive coordinator Chan Gailey challenged Haley’s credibility as a head coach. Johnson was suspended and then released, and Gailey was fired.

Over the course of those three seasons, the Chiefs went a pitiful 21-27, but even uglier were their nERD scores. Haley’s 10-6 finish in 2010, when the Chiefs won the AFC West with Matt Cassel and Jamaal Charles leading the way, accrued just 0.30 nERD. In his other two years, Haley’s Chiefs had scores lower than -5.00 nERD. He’s had a much better time since, as the offensive coordinator for the Pittsburgh Steelers, who have had two consecutive top-10 total scoring seasons in 2014 and 2015.
