One thing Jimmy Johnson was sure to do was inject some veteran leadership into the team.
Don't get me wrong the team was built by the draft but it was also peppered with a few veterans in the right places.
Tony Casilles, Ray Horton, Thomas Everett, these guys led the defense. They also had their homegrown veterans like Mark Tuinei and Bill Bates. These guys added the maturity element.
This is where guys like Zack Martin, Tyron Smith, Demarcus Lawrence and Dak Prescott need to accept the role of veteran leadership by taking it to a higher level that they ever have before.
