I've felt sorry for Tyson at times, he never seemed to be right after Cus died.
Tyson reminded me so much of Joe Frazier when he was 20. That hard to hit bob-and-weave style, with a devastating punch.
Then Don King got hold of him.
I think Tyson was already on the edge of the cliff except that D'Amato was able to keep him from going over, much like Chuck Daly was able to keep Dennis Rodman from going over. Then, along comes someone who wants to exploit a fragile personality, or simply not capable of recognizing the need.
