Could have easily been a bigger star if used properly. Guy literally carried the UWF during its short existence. When NWA/WCW bought out UWF, they purged most of the roster and kept a few(including Williams). Had a pointless match with Barry Windham at Starrcade 87, and after that was a member of the Varsity Club(who I hated) and had a decent run with the NWA belts.
After that it was pretty much over, although I assume he dabbled in wrestling afterwards.

At the rate all these 80s legends are dying, there wont be any left within 10 years even though they aren't really that old.
