Roy Jones got KO'd recently, and it got me thinking: What caused him to decline as much as he has? Did losing all that weight from HW really take that much out of him? It's not like he grew old overnight, contrary to what people say. You could see all the way back in the Harmon fight that he was noticeably slower.
When you rely on physicality and chemicals most of your career and then age hampers that physicality and the reality sets in that you cant use peds indefinately and combine that with seemingly believing your own ridiculous hype then this is what happens.
