Re: which era had the highest ratio of crooked top level fights?
I don't know which era was the worst.
Mobsters Frankie Carbo and Blinky Palermo controlled most of the welter and middleweight fights during the '40s and '50s. Kid Gavalan fought a number of fixed fights under Carbo. Carbo also owned Liston for a while.
I don't think Marciano and Patterson fought fixed fights. Marciano said he was offered more money than he had ever seen before to throw the ****ell fight and turned it down. I believe him.
I think the Liston-Clay fights were fixed- I'm certain the second one was.
I believe Ali fought several other fixed fights. I don't think his opponents threw the fights, but I think the judges and ref were in the tank.
Worst era- Who knows. Maybe they were all the same including now.
