In the 70’s Mayfield was as big and strong as anyone. Hardly a David situation then.

Correct. In the 70's and 80's, Coach Jack Morris liked to run it, 3 yards and a cloud of dust. Coach Leahy opened it up a little more during his tenue from 93 to 98, but, now, Coach Joe and staff have really opened it up and taken the air attack to a whole new level, especially since the late 00's. The defenses of those earlier era teams were also typically very stout. More physical than finesse.
