I see that you copied nearly word-for-word what Bill Washinski said in his August 3rd article about Cowher. You conveniently omitted the rest.
"When Noll retired, he told his wife that the Steelers were a Super Bowl team, but he was no longer the man to guide them. But when Bill Cowher said he saw “no apparent weaknesses” entering the 1992 season, few took him seriously. He proved the doubters wrong as he led the Steelers to an 11-5 record, securing the AFC Central Division and the #1 seed in the AFC.
To say there were no challenges would not be the same thing. Noll was disengaged in his final years, and it was felt throughout the team. The offense and defense had a divide that continued to grow. Offensive players were so frustrated with Joe Walton that only a last-minute interference by Noll prevented the offense from boycotting the coordinator. The players were not united and were going their own way."
Maybe Noll and Cowher believed it, but they were about it. A huge team divide and coming off of a 7-9 record...yeah, sure, sounds like Super Bowl material.
By the way, the Steelers didn't even win a single playoff game that year. They got spanked 24-3 at home in the first round. You forgot that part, too.
