Tyson DID have heart.

he had heart in the ring pre-prison, and heart in the short term over a few years max, but he didn't have the long term heart, no one can deny he didn't.

 

Tyson was short but never tiny, he handled most of the big guys pretty handily and not until King got into the picture and pushed out Rooney and the gang did Mike start to dissolve. I dont think the taller,bigger men were the problem,Douglas was timing and a get off the floor in the 8th comeback and Mike fizzle by 10, Evander was not a Big man and for Lewis he was toasty

I think we will never know how good Tyson could have been had Cus finished his business and Don King not poisoned the flesh

A few things he never overcame and himself being #1 on the list
