Probably not as much as you think, because he really wasn't that good of a football player and made his name as a situational fullback. The Cowboys offensive lines of the early 90s are probably the blueprint for the current NFL offensive lines. Those guys were freaking enormous compared to the average line, and it's the main reason why Emmitt Smith is a household name.
The Cowboys themselves were modeled after the Hogs and Giants offensive lines of the 80's. The competing archtype in the late 80's early 90's was the lighter, more agile offensive lines of the 49ers.
I'd agree with that. The 49ers of that era were able to benefit from a lack of a salary cap. They were stacked across the board. It was the place you went when you were an aging star who wanted to win a ring. They wanted those more nimble guys because of the crazy pass rush of the other teams in their division and conference.
