I just go to youtube and type in various games in the search bar. The 1989 game was only posted in June of this year, and I had NEVER seen it in its entirety until I read about it in a link. The sad part is that many great USM games have not been uploaded to youtube. For example, I have YET to be able to see the 1987 NIT championship game, 29 years after the fact. The only clip I found was the opening of the game posted by a LaSalle fan.
The funny thing is the opposing teams are the ones that usually upload the videos. I'm not sure why our own fans won't do it. 26 years later, I've never seen that game.
