Poop Master Flex
Mid-Card Championship Winner
Now I don't really know how well wrestlers drew in crowds in the 50's and 60's, but everytime I look up superstars from that time period I see the name The Crusher.
If I trust in Wikipedia, he is in 4 different wrestling Hall of Fames, including WCW's. He had a highly successful run as tag-team champion in 3 or 4 different territories, back when a Tag Team match had to have been something special. And went on to hold the AWA's World Heavyweight Championship 3 different times, his last run unifying his belt with the Omaha version.
Sounds like a guy people paid to see.
He was over no question but he wasn't the top guy. I gotta give you props for mentioning my favorite pre Hogan era wrestler though. Mr. Saloon was such a unique and charismatic wrestler but he worked for a promotion that was dominated by 2 guys for over 20 years.
