From Bill Cowher’s book; it wasn’t all sunshine and roses, especially through those 1st 6 years. They had a lot of locker room drama; but also had the leadership to check teammates too.
I wouldn't doubt it. Wasn't he the youngest HC ever hired at that time (if I'm off, apologies), and was also because of the departure of a living legend in Chuck Noll. All that matters are the end results, which were pretty damn good.
