That's why he can afford to pay $90 million to running backs who always fumble the ball.
When Jerry Jones paid Deion Sanders to lure him from San Francisco it was the beginning of the end for the Cowboys. He became convinced that he had an eye for talent, and was just one big signing away from the Super Bowl every year.
Y'know when I gave up on the Cowboys? Under Jerry's direction, the Cowboys had produced three straight 5-11 seasons. Jones couldn't get funding to build Jerry World. So, he hires Bill Parcells, and lets him actually coach. How good a coach was Parcells? He made the playoffs with Quincy Frikkin Carter.
Cowboys make the playoffs. Jerry gets deal for Jerry World signed. The next day, over Parcells' objections, Jerry signs Terrell Owens. Bill retires. That's when I quit watching the Cowboys. Later I realized I wasn't an NFL fan, I was a Cowboys fan, and quit watching pro football all together.
Cowboys run on the fumes of Parcells' teams for another season with Jerry puppet Wade Phillips as alleged coach. I never saw a Jason Garrett coached game, but did see a few clips of him icing his own kicker, etc. I don't even know who the new coach is, but the press conference when he was announced looked like a POW video.
