Do you know what the article means by: "why some become Muhammad Ali and others Mike Tyson"?
I think it's contrasting the success of Ali with the (inferred) lack thereof of Tyson. Maybe? But that doesn't make any sense to me; the first paragraph of Tyson's Wikipedia page will tell you why.
Unless it's talking about social success. In which case it seems out of context of the article.
I know very little about boxing, so I'm really not sure. My thought would be that though both were successful, perhaps Ali was an underdog who became successful where Tyson started successful but hit a plateau? I have no idea whether or not that maps to reality, that's just pattern matching. The other possibility is that the author of the article knows the same amount about boxing as I do, and chose an unfortunate analogy.
