That's giving him way too much credit. It implies that there was a time when he was actually a successful football guy. There wasn't. 89-95 was all due to Jimmy. As soon as he was gone and his players started going elsewhere and/or diminishing due to age or injury, the Cowboys ceased to be a genuine championship contender.
He has a fundamental lack of respect for the head coach as the guy who provides vision, direction, and strategy for the football side of things. It's why coaches he's hired in the years since can't pick their own coordinators and why you get dingbat comments from him and his dingbat son to the effect of "oh, the Saints were hot, we just ran into a hot team." They genuinely think it's just a matter of getting hot at the right time.
I really can't stand these fools.
