When the Pittsburgh Steelers take the field tomorrow two branches of one of the biggest coaching tree’s in the modern NFL will clash. Andy Reid, the Kansas City Chiefs head coach, and Steelers head coach Mike Tomlin can both trace their coaching lineage to Mike Holmgren. I hope the diagram below helps.
While they are essentially on different sides of the Holmgren coaching tree, it hasn’t stopped Reid from fielding tough teams on Sundays. Reid is 3-3 all-time against the Steelers.
