Does anybody know the story behind it?
got laughed off the field. The first thing they did to Walk Ons, which wasn't in the movie, was time you in the 40 yard dash. I ran a 4.7. I still remember what one of the Assistant Coaches told me: "We have Defensive Ends running 4.9" (meaning Ross Browner and Willie Fry). They had unbelievable talent back then.
out for the DE position and just proved you were faster than them
I remember a small group starting to chant something near the end. Then I picked up they werecsaying “Rudy...Rudy..”. Others started doing it and then he went in the game. There was lots of cheering when he got the sack
the chanting started before the end of the game in the middle of the 4th quarter based upon the article in the Observer about Rudy that week. He wasn't on the KO team like the movie had him but he did line up at left end and chase the QB from behind just like the movie.
I hadn't read the Observer article, and they were already aware of what was going on, being friends with some of the players, and were joining in on the chant. Then he got in, and the student section, and then the crowd in general reacted to his play.
