Both are clearly amongst the highest echelon of slimeballs.. I think at present it's obviously Arum who is hurting the sport moreso, only because for whatever reason Don King doesn't really have the same kind of roster he once did. I always wondered how King was able to get to where he was though, I mean you'd listen to the guy and assume he's virtually retarded. Arum comes across like any other sort of waspy lawyer type, it's not such a mystery and for that reason I think he's a lot less endearing. Don King must have been a far harder man back in the day.
