Mickey Walker vs Roberto Duran at Middleweight. Both guys moved up to fight at higher weights than their "prime". Both won a "Middleweight" title, with Duran losing 3 shots at a Supermiddleweight title, and Walker (165lbs) lost by SD to Tommy Loughran for the LtHvy title. Walker of course had some "success" at hvyweight, weighing around 175lbs . Walker: 5' 7", 67" reach Duran: 5' 7", 66" reach Who wins?
Gotta go with Walker he was a bulldog and his stamina must have been something else to fight with Greb at the pace they were said to have fought at...it would be a good fight
It would be similar to Duran v Barkley ..but with Duran being on the losing side .Good entertaining fight.
