Cowboys fans will always hate Romo for not being the second coming of Aikman or Staubach, because to them anybody who isn't a Hall of Famer is a trash. It's an infantile way to view the world, but whatever, there's no changing it.
In the NFL it almost always takes a strong organization years of fielding strong teams to break through and win a Super Bowl. But the Cowboys could never put a good team on the field in back-to-back seasons.
The Patriots have Tom Brady, Bill Belichick, and are the best in the league at gaming the draft, salary cap, free agency and comp pick systems in the modern era. They fail most seasons anyway. The Cowboys had Wade, training wheels Garrett, and Jerry's drunk wheeling-dealing. Why do people think that should have won the Cowboys a darn thing?
