Which fighter was most invested in?

I believe it was Tyson. How many people, not just fighters were given so much? Yes, I know he had a rough childhood up to some point in time, but since then D'Amato made up for it, did he not?

I know Sanchez got personal physician and trainer, but I believe that Tyson got more.

Anyone got more than Tyson?

 

It is not about who earned the most.
It is about who got the most expensive grooming, training and other costs.

 

When did you learn to spell? :think

 

in terms of cost alone, Oscar de lay hoya was given crazy money to start his pro career, so was sugar ray leonard. Even Audley harrisson was given 1 million uk sterling for his first 10 pro fights. I doubt even Anthony Joshua got this 10 years later. Lewis and bowe too.
In terms of total investment such as coaching time and quality I think all the above had done quite well. all of these were coached for years at club level hen on international amateur programmes travelling the world competing in tournaments. (not cheap).
Tyson had top pro coaching from an early age and a lot of money pumped into akeeping the destroyer busy (again not cheap) not to mention the cost of the publicity campaign. Tyson too was well looked after.

 

Considering he's not really gifted in any way physically, Chavez Jr. had to be high up the list.

 

Barry Hearn invested/risked millions in Chris Eubank. His whole company Matchroom Sport was on the line at the NEC when Eubank met Benn.
