Marvelous Marvin Hagler moves up to fight WBC Champion John Conteh, 175 lbs, 15 rounds.

Marvin fought at maximum effectiveness at 160lbs.

 

Perhaps. But Dwight Qawi was only like 5’6” and he was a terror at light heavy and cruiser

 

Was Qawi really a terror or a big ol' teddy bear

 

If Mathew Franklin were alive I’d urge you to ask him

 

Leon Spinks wasn't so terrorized by Qawi

 

Nah he was just KTFO

 

Probably would look like the same climb in weight Napoles did to fight Monzon .. he was just too small

 

Marvin was simply just well suited to middleweight I certainly can’t see him being a more effective fighter putting on the pounds.
Moving up to fight a Conteh is a huge task Conteh besides being a specimen was a highly skilled operator who in his prime was also a dirty so and so.
This one wouldn’t be advisable for Marvin.
