Re: if Cus D'Amato hadent died when he did.....
Cus by himself would have found Tyson too much of a handful, eventually. However, with Jimmy Jacobs in tow, team Tyson could have kept the reigns on Iron Mike.
These were the two men who Tyson looked up to and respected above all others. Someone like King would not have had the influence over Tyson that he eventually did if Cus and Jacobs were around.
D'Amato died relatively early into Tyson's pro career, but Jacobs stayed around much longer than that and died in '88. Before his death, the lid was kept on Tyson for the most part.
It's only after Jacobs' death that things went to shit. The final nail in the coffin was when Rooney was sacked.
Having said that, Tyson was 37-0 before he met Douglas, and a world away from 50-0. I think that 50-0 would have been a bridge too far for Tyson, even if he had all three of the 'holy trinity' behind him.
However, there probably would have been no Tokyo and his legacy would have looked a damn side better than it does.
