Not new here, but...
#1 OU had been upset by KU the week before and had to go to Mizoo to play. don't know that it defined OU, but it kept them in the hunt for the MNC in 1975, which they did end winning. OU is down by 7 late in the game and it is 4th down. Joe gets the pitch and makes a great 75 yard run to tie the game. You'll have to watch the rest.
