New Tennessee Titans head coach Brian Callahan started his coaching career with the Denver Broncos. While he was there, he worked with Hall of Fame quarterback Peyton Manning. Callahan talked about his experience working with Peyton on Peter Schrager’s podcast The Season. That’s a really good listen to learn about Callahan’s coaching background.
Anyway, Callahan said on that podcast that being a young guy in his first coaching job, he had to earn the trust of Manning. That’s not an easy thing to do, but Callahan eventually earned Peyton’s trust showing his work ethic and knowledge of the game.
