Three of the best five Black head coaches got hired BEFORE the “Rooney Rule.”
Art Shell (Raiders), Dennis Green (Vikings), and Tony Dungy (Colts + Peyton Manning). Shell and Green messed up their W/L percentage by returning years after retirement to coach again.
Mike Tomlin (Steelers) has been my favorite Black head coach since 2007.
Marvin Lewis (Bengals) had six excellent seasons from 2009-2015. But, he was 0-7 in the playoffs, and his last three seasons clearly forced his retirement.
So - 23 Black coaches in the last 40 years, and five of them were clearly above average. About 22%.
I will speculate that the percentage for above average white coaches is roughly the same or higher.
Agreed. One more thing... teams may be shy about hiring a black head coach because they don't want to face charges of racism when he is inevitably fired.
