Contenders who could have been champions with massive state support?

Which contenders throughout history would have won the championship if they'd gotten a huge infusion of support from their national governments?

By this, I mean essentially a blank cheque to get the best trainers, nutritionists (and maybe also "nutritionists"...), sparring partners, full time camps year round, and so on. A level of state support you might expect from a wealthy totalitarian government that sees you as a vital component to its own propaganda effort. Very rare in practice; I'm not even sure Schmeling or Carnera got it. We're talking the Manhattan Project of boxing here.

There are some obvious examples in the Depression, like Walcott. But I'm curious whether anything changes for any fighters who already had decent-but-not-ridiculous support already. The Youngs, Witherspoons, and the like.

No bribes or assassinations, though. The victories have to be legit.

 

Yeah. The Communist Bloc generally isn't a bad source for fighters who might pull it off. (Though Ali, who sparred a couple of Russia's top guys, commented that they were essentially extremely skilled amateurs in terms of their abilities, not comparable to top professionals.) In terms of other totalitarian regimes who didn't have the amateur restriction, Nazi Germany might have produced something if WW2 hadn't happened. They seem to have been like the Soviet Union + a pro scene. And German chemical labs were some of the first to synthesize steroids, so they'd even have the chemical assistance that the Soviets did, but before everybody else.

As it was, the Nazis fortunately got crushed in WW2, so we never got to see whether they could have produced anybody capable of beating Louis, Charles, Walcott, or Marciano. I don't know, personally. Hein Ten Hoff was one of their best, brought up under the Nazi amateur system and everything, but Walcott apparently toyed with him. Whether Walcott could have toyed with a hypothetical version of Hoff (or others like him) who'd been training in peacetime with full state support through the 1930s/40s and were possibly on PEDs to boot...less sure on that one.
