First of all, to say Romo isn't a Super Bowl caliber QB is a joke. Eli, Flacco, Big Ben, Kap, Hassleback, Dilfer and others all won or got real close to winning a title. Romo is just as good. Saying he has to carry the entire team on his back is not the standard. He is more than capable of doing his part with the offense to win. He just needs the Defense, Special Teams and coaches to do their jobs. They don't have to dominate, but they can't lose the game and expect Romo to overcome it alone. Not many QBs can, but those were the truly elite- Brady, Peyton, Brees.
As for Jones, I think most of us old-timers don't fully appreciate what the Landry teams accomplished. Yes it was before the salary cap and major free agency, but their dominance spoiled us. Then we got the JJs and 3 more titles very quickly. I just think with our past success, JJ never took the time to do a real re-build after the glory years. He thought they could keep putting winners on the field every year with just the star on the helmet and throwing lots of cash and big names at the problem. I'm fairly certain that winning and competing for Super Bowls every year like the Landry teams did would make JJ a heckuva a lot more money than he is making going .500 for 15+ years. I honestly believe he wants to win more than just making money, but he was never realistic about our players and coaches for too long. His early success led to either arrogance or ignorance, but I don't think he's intentionally sacrificing winning for dollars.
