I just rewatched Coleman/Williams. After Pete Williams knocks Coleman out one of the announcers say, "And the Lion's Den is victorious yet again!"
It made me wonder what it is that causes a fight camp to go from being one of the best in the world to toiling in obscurity with no notable fighters or notable wins. I don't know. But the Lion's Den, Hammer House and MFS are all dead as far as I can tell.
