Levrone looked phenomenal at the start, 1991-1992, legs where there, back was half good, great lat spread from front and rear, but weak BDB... After he had few good shows, like 1995 Olympia and 1994 ASC, but he regressed year after year, legs completely gone around late 90s, looking more and more only upper arms and shoulders... Oliva had incredible genetic, had everything, structure, muscle bellies, proportions, symmetry, but king of the genetic hill will always be Dillett in my opinion, who also had the height contrary to Oliva... Like Nether Animal rightly said, it was not only a matter of work ethic... Yes, he had a lousy diet, mostly never worked hard enough coasting on his unmatched gifts, but he also had injuries/surgeries and chronic asthma, and he almost died for an idiotic advice on diuretics...
