Met quite a few BYU fans in 1992
All of them were respectful people, and were quite happy to engage in friendly conversation.
I ran into some of them at a local pancake / waffle restaurant the day after the game, and they were very pleasant people. Seating was sparse, since the place was packed, and they asked me if I wanted to sit with them. I gladly accepted.
I have to admit, they were very well versed in the college football game.
One of them noted that our defense finally found its identity that game in the 2nd half, and if we had a rematch that day, Michigan and Stanford would have been blown out by us.
They were especially impressed with John "Shaft" Covington (played mostly outside linebacker that game) and Demetrius DuBose, since those guys were laying some serious wood on their WR and TE in the 2nd half. Those catches that the receivers were making in 1H became dropped passes after getting hit in 2H.
They were quite surprised that Bobby Taylor was a true freshman.
They also got a laugh out of Rick Mirer's pathetic shanked punt that went for less than 10 yards.
I came away from that breakfast with a positive impression of their fans, and I suspect that if I ran into more of their fans in this day and age, they'd be similar kinds of folks.
They're basically the opposite of what I've seen out of Boston College fans.
