ND played Stanford at home in 1992, and lost, costing us any chance of playing for the championship since we had already tied Michigan.
After that game was the practice with the famous Joe Moore batting practice, with the OL puking. I think you can find the story as told by Aaron Taylor.
After that game, ND dominated the line of scrimmage for the rest of the season. Joe Moore told the OL that they needed to be able to tell the Defense the snap count and what hole they were going to and still be able to move the football. I guess fear of another practice like the batting practice one will inspire any offensive lineman to block better.
