Lets address the whole Tyson V Ali thing, Ali wins hands down, period. Remember Ali had an incredible jaw so he could take Tyson's punches, just watch Holyfield v Tyson 1 to see how to dismantle Tyson...clinical!!
You are right if you're referring to after 1990, when Tyson lost to Dougless in Tokyo, Japan. But from 1985 till the fight with Big Buster he was unstoppable and dangerous, and I'm sure would have won. If you have ever watched Tyson fight back then you'd know that. After Tyson fired his first professional trainer Kevin Rooney in early 1990 and was persuaded by Black mob Godfather Don King, and started hanging around the Black Power crowd is when Tyson totally started to suck big. He went down hill after that. Then he went to prison for that rape and got out in 1995. Telling Kevin to leave, drugs, drinking, Don King, women and prison is what messed Mike Tyson up.
