Winning in the NFL doesn’t come from doing the easy things. It comes from doing what’s difficult and doing those things well. Bill Belichick didn’t win all those Super Bowls by clapping and telling his players they did a good job. He did it by pushing his best players to be better. While he may have been cutting some corners, too, the point is that no matter how incredible a player is, a great coach always pushes them to be better. Mike Tomlin seems to understand this perfectly, which may be part of the reason for his long-running success.
