There are a couple of things that really fascinate me about this game.
First, the lack of formation changes. I watched the last 6 minutes of the game which included Nebraska's game winning drive. The only formation they ran had 5 linemen, 2 tight-ends with one off the line of scrimmage, a wide out, and then a power I set with Tagge, the FB, and Kinnie. Think about how hard some coaches try to confuse and out-scheme teams formationally in this day and age, yet Nebraska was able to put together outstanding offensive performances with minimal formation changes. Pretty remarkable.
Second, is the size of players. Near the end of the game, the announcer said "Look at the size of that man (in reference to Rich Glover). The guy is 6'6" and 250 pounds". Now-a-days, that's 50 pounds too small to be a DT AT LEAST. 250 is what your average defensive end weighs these days. Pretty amazing stuff, to think that in 50 years the average weight of a DT has gone up nearly 50 pounds.
