It’s been nearly a decade since Bill Cowher stopped coaching, but that hasn’t done much to keep his name out of the rumor mill every December and January. After all, Cowher was both very successful and very young when he retired, and NFL folks believe those dots can be connected to mean he won’t stay retired forever.
That made me wonder: how much of an outlier is Cowher with respect to his age and how successful he was? In particular, Cowher was successful at the end of his stint, which differentiates him from someone like Jon Gruden. Defining “success” is challenging when it comes to coaches, but I want to just generate a set of comparable modern coaches and see how they fared at the ends of their careers and when they retired. I don’t need a particularly precise coaching formula, just something that gets the job done.
As it turns out, six years ago, I created a rudimentary formula to rank head coaching records. Let’s use Cowher’s last three years as an example. This formula gives credit for wins above losses, so Cowher gets a 0 for his work in 2006, his final year, when Pittsburgh went 8-8. The prior year, the Steelers went 11-5, so that’s +6, but I also gave a 12-point bonus for winning the Super Bowl, so he gets a +18 for that season. And in ’04, Pittsburgh went 15-1, so that’s +14. Add it up, and Cowher has a +32 score over his last 3 years. And he was just 49 years old during his final season. [click to continue…]
