Mike Tomlin, now there is one guy who could be from any era. People may say he is a throwback coach with his tough-love style, but his style fits his players. That’s what people sometimes don’t understand. What makes a leader is taking the pieces you have and finding ways to motivate, to lead, to make them better. That is what builds championships.

The Packers were a team that stood by each other off the field. You were a “Pack-a” — and no matter where you came from, what color your skin was, what religion you were, you were part of a one single unit. We had zero tolerance for bigotry. We wanted the best players and found ways to make every player better.

That’s what Tomlin has done in Pittsburgh. They have had issues off the field, but it has not affected the focus of the team or the way the team carried itself. They play with pride, with respect and with honor. They come from varied backgrounds and play for a coach who is reflective of that organization he represents.

Maybe that wasn’t always true in every NFL city, but it is true in Pittsburgh. The team has become a reflection of the community and the great pride that everyone has in what the Steelers stand for, just like the way all of Green Bay believes in the Packers. That is built over time, it does not come without great sacrifice, and it is not something that can be trivialized. Tomlin can coach in any era.
