Heck No. Because he would have demanded Football control and leadership. This is what real Head Coaches require. Do you realize what a leadership combination Urban Meyer and Dak Prescott would have on this Cowboys team.
Look at Urban Meyer track record. He leads teams to undefeated seasons and championship and has coached on every level but the NFL just like that other Cowboys Head Coach that Tex, Gil, and John Wooten recurited named Jimmy Johnson.
Plus Urban Meyer has that unique eye that Jimmy Johnson had for talent. Not the talent present but the talent to groom to stardom. See Alex Smith and Tim Tebow. The man went undefeated with teams QB by Alex Smith, Tim Tebow, and the 3 headed monster of Cardale Jones, Braxton Miller, and J. T. Barrett. Then look at the NFL prospects that came out of his Head Coaching from Bowling Green, Utah, Florida, and Ohio St., who has put out more prospects in the NFL than the U in the 80's. Maybe not the U in the 80's but darn close.
Again, Jerry Jones does not care about winning Super Bowls. He cares about being the Owner in total control of America's Team. Results do not matter now. As he said, he has his stadium.
