....would he likely be able to get the belts and become champion in each division or just is it too far removed for him?
Srr is a product of his hard times though. Also lack of sports nutrition and modern training make it a different person. But hypothetically teleported into these divisions he destroys them all of course. How can you argue against the goat over these fight 1/2 times a year modern boxers?
His only problem would be 160-168-175 pounds. These guys are mostly 1-2 weight divisions bigger by fight time.
I think 160 would be his ceiling. But he could likely go down lower and rehydrate. 135-160 he could probably dominate over the course of a career
