Aside from a few tweaks, what transpired in the cage that day in terms of rules and regulations wasn't much different than what you'd see today. Of course, as the sport has evolved, so too has the level and skillset of the modern amateur fighter. Still, it was pretty cool. And of those who stepped into the cage that day, one - Greg Soto - eventually made his way to the UFC.
History, man. Isn't it great?
