Mike McCarthy sold himself in job interviews as a “new” coach, even though he has a long history as a coach. His year off was spent re-examining everything he had done as a coach in the past, and looking at everything in today’s NFL in an effort to evolve as a coach. He was selling a coach who was re-inventing himself, one who was keeping the good parts of his past and discarding things that were outdated.
It appears as he is selling the same message to the rest of his coaching staff.
