It has never been a Jerry Jones' game, at any age. He won because of Jimmy Johnson, period. He made a great decision in 1989, almost everything since has been slop.
The Super Bowl they won under Switzer was with a greatly diminished team. He wasted the back of half of the Triplets' careers, wasted a host of good players since, because he had no idea how to hire a coach, had no idea how to construct a roster, rejected the idea that his coach had to run the lockerroom and be the face of the team. And his enormous ego means he'll never be able to address any of those issues, it will only be left to someone else when the old fool is beyond keeping up the pretense of running the show when his mind is totally shot. Sucks for Cowboy fans, especially young ones who've never seen a real winner. We can argue Dak or Fat Mike or whoever, but they're just discussion topics, no more the real reason for failure than those of us talking about it on a message board.
