So many are understandably picking Roger Staubach. Others are understandably picking Troy Aikman or Tony Romo. But...Dak has a better career completions percentage and is on pace to shatter Romo's franchise record total passing yards in 4 more years if Dak stays healthy. So, I will stick with Dak since he's currently on the team.
But...if I had to choose an all-time Cowboys great to help this current team, I would choose The Playmaker, arguably our franchise's best ever WR, Michael Irvin. Imagine opposing Defenses trying to stop Irvin teamed up with CeeDee and Gallup at WR, plus Schultz, McKeon and Ferguson at TE? This receiving corps would be unstoppable.
