in 77, Ali = Chris Byrd with a better jab. therefore, Chris Byrd with a better jab vs. tyson anytime pre-2000, i'm going with Tyson.
wow, there are a lot of extremists for both sides...! i consider myself moderate. don't insult the great Muhammad Ali by comparing him to Chris Byrd! The 1977 version could actually pull an upset (little chance) whereas Chris Byrd would have ZERO chance. 1977 version would unlikely get KO'd as it is near impossible to do but Chris Byrd would get destroyed!
I can't believe this. Post-prison Tyson was NOT shot. He was still an excellent fighter. Ali in 1977 was NOT. I love Ali, he is my favourite fighter, but in 1977 he just looked awful. He managed to beat Shavers, but Shavers was no Tyson - even a post-prison Tyson. His reflexes were gone, his speed was nearly gone, all he had left was a chin and heart, and the ability to clinch. Tyson would stop Ali, though I don't think it would be KO. It would be Dundee throwing in the towel. Prime for prime - Ali takes him.
This post should say it all. C.M. always gives Ali the benefit of the doubt. If even he doesn't pick his hero in a match up, Ali has no chance! Ali should have retired at the very latest after Frazier III. After this, any really good worldclass heavyweight beats him. Prime for prime I'd bet on Ali.
