Notice that receivers on wishbone teams were not ever being sandwiched and crushed by two or three defenders...
That's because to have any hope of stopping that wishbone ground game you had to have nine or ten guys close up on the line of scrimmage. A receiver on a wishbone team had to worry about being tackled by one guy running wish him, that was all.
Bear Bryant perfected a passing game keyed to the wishbone in the late 70s and won two national titles with that system before he died. Nobody ever figured that one out.
That 1971 Oklahoma/Kansas State game remains the all time record for rushing yardage in a single NCAA game to this day.
A favorite topic... This was the only situation I ever saw in which an amateur version of a sport appeared to have outgrown the pro version. If there had been a college all star game in the late 70s and if Paul Bryant had been allowed to coach the all stars and use his own offense, the NFL could easily have been seriously embarrassed.
