No. Tyson's slide happened after Cus passed away. After Kevin Rooney was fired as his trainer, a trainer who worked with Mike under D'Amato, his career went to hell.
Don King. Robin Givens. The rest is history.
Tyson has said that Cus used to tell him "there are animals out there disguised as people and you aren't smart enough to sort them out"
Cus was a pretty smart man...
The last time I paid or watched HBO was when Tyson was boxing for them. That was a long time ago. Mike Tyson still scares me though. My memories of him were when he was crushing the world in the first round.
