Perceptive post, other than Tomlin's job is still very secure unless the team falls apart, and a 13-3 regular season doesn't indicate that being on the horizon. Of course it could happen in rapid fashion when Big Ben retires. They're also fortunate to have the league's best receiver in Antonio Brown and one of the top three running backs in Leveon Bell. Long-time GM Kevin Colbert, who keeps a super-low profile, is a Caste disciple but overall drafts well and is shrewd enough to secure key components like Big Ben, guard David DeCastro, T. J. Watt, and the team's long-time former tight end Heath Miller.
Tomlin is smart but he isn't an Xs and Os coach, and he's not a strategist. He's basically the black players' buddy, one of them just older. He's arrogant and scratch the surface and you'll find a committed BLM type militant. He can barely contain his thug impulses and he hired a genuine thug in his best buddy Joey Porter to be the linebacker coach. What a joke hire that was.
The team's culture is all about having fun and the black stars are prima donnas who regularly stir up drama. Not a recipe for winning a Super Bowl. But Tomlin did win a Super Bowl early on with what Bill Cowher left him and has an excellent regular season record and as long as that continues his job is secure. He's really the poster boy for the Rooney Rule, and he's on the Rooneys' team, so I fully expect him to be around for a long time. Unlike the other teams where head coaches are being made the fall guys for the failure of black quarterbacks, on the Steelers it will be assistant coaches who will take the fall for Tomlin's shortcomings.
