Pick a Champion... imagine him against every Champion in his division... ever! Could he win, yes or no? Just a yes or no is required but if you wanna add more feel free. Holyfield (CW)- WBC- Camel- yes DeLeon- yes/did Gordon- yes Ratliff- yes Benton- yes Duran- yes Wamba- yes Dominguez- yes Gomez- yes Braithwaite- yes Mormeck- yes Bell- yes Haye- yes Fragomeni- yes Erdei- yes Wlodarczyk- yes IBF- Murphy- yes Parkey- yes/did McCrory- yes Lampkin- yes Warring- yes Cole- yes Washington- yes Grant- yes Mayfield- yes Williams- yes Jirov- yes Toney- yes (lost to Toney at HW when he was 137 years old) Davis- yes Bell- yes Cunningham- yes WBA- Ocasio- yes/did Crous- yes Qawi- yes/did x2 Belbouli- yes Daniels- yes Czyz- yes/did (at HW) Norris- yes Miller- yes Tiozzo- yes Hill- yes Arslan- yes Jones- yes Adamek- yes WBO- Pultz- yes Havnaa- yes Booze- yes/did Bott- yes Giovannini- yes Michalczewski- yes R. Rocchigiani- yes Thompson- yes Nelson- yes Maccarinelli - yes Ramirez- yes Huck- yes Toughest fights? Qawi was very tough for Holyfield in their first fight WSD15. It was only Holyfield's 12th pro fight though. Holyfield stopped him in 4 in the rematch. the onkly other fighter to stop Qawi was Foreman (KO7). Others that might give him trouble are- Haye, Adamek, Cole, Norris, Toney, and Cunningham... but probably not too much trouble.
Benny Leonard @ lightweight I don't fell like typing or copy/pasting the name of every lightweight champion. The answer for each is Yes. His youghest bouts are Prenell Whitaker, Shane Mosley and Ike Williams.
I think JMW would be interesting. Ray Leonard, Hearns, McCallum, Benitez, Duran, Julian Jackson, Norris, Curry, Mosley, Wright, DeLaHoya, Trinidad, and some others. How about Ray Leonard at JMW? Could he beat all of the JMW Champs on his best day? Would he lose to any?
