The question is.....did Aikman DEMAND they play at that level, or was he just lucky to have them?
I guess once they won their Super Bowls and Jimmy left Troy stopped "demanding" they play at that level. The bottom line is once Jimmy's influence wore off no amount of Troy "demanding" was going to produce anything. Jimmy drove that bus PERIOD! Leadership starts at the top and filters down. Granted you have to have leaders on the team, but if all you have is a puppet for a head coach then that leadership ain't gonna amount to much.
We can argue all day long about Romo. However, until Jerry changes the way he does things it won't matter who the QB is. The Cowboys have very little talent on Defense. It remains to be seen how good of a DC RR can be. The same goes for JG as the HC/OC. Still, as long as Jerry runs the show it won't matter. His idol was Al Davis; he has now successfully turned the Cowboys into Al Davis' raiders.
