Troy Aikman and the Dallas Cowboys of the 1990s are having a reunion. They rent a bus and go on a cross-Texas tour. At one point on the tour, the bus pulls into a gas station and out comes Steve Walsh to pump their gas.
Aikman looks at his former teammates and says "Wow guys, imagine, if you had traded me instead of him in 1990, you would have had a gas station guy for a quarterback."
Jimmy Johnson looks at Troy with a smile and says "No, Troy, if we'd traded you instead of him, he would have won three Super Bowls."
Staubach was a better overall quarterback, was better with respect to his league, and led the Cowboys to four Super Bowls.
Staubach also missed almost all of his twenties due to Navy commitments, and didn't play his first full season until the age of 29.
Given that he led the NFL in passer rating and went 85-29 with four Super Bowl appearances, Staubach might have been the greatest quarterback of all time if not for his Navy duty.
