He could do a world retorement tour like Jones has been doing in recent years. He just needs to skip the part where he fights at too high a level past his prime like Jones and skip straight to the eastern European/Middle eastern journeymen part
nope because Hagler fought Hamsho Mugabi Leonard Hearns Duran Briscoe when his own weight class was one of the most stacked of all time while Floyd fights washed up Oscar, 40 year old Mosley, Marquez undersized by 2 weight classes + Floyd not making weight etc. Hagler also weighed as low as 157 so he was not a big middleweight compared to light heavyweight spinks moving up to heavyweight 152 lb Floyd fighting middleweight Golovkin/Martinez up just one weight class is not as big a disadvantage as Hagler going up 2 classes to fight Spinks, who on top of being a bigger size disparity is way more accomplished than either of those two. He wouldnt even fight Paul Williams
