Joe Louis's durability would play key here. Tyson would have pure advantage for the beginning rounds but would not last. Joe had great killer instinct and combination punches to follow.
Why would Louis have to incorporate some movement? It's not like he doesn't have IMMENSE firepower of his own. You label Louis too slow yet he had some of the fastest hands in the divisions history and to make that even more effective he was the best combination puncher in the history of the division. As a matter of fact he's considered by most to be the "greatest" puncher in history. So no Joe doesn't necessarily have to change his entire style whatsoever. Perceived weaknesses in his footwork don't matter here as he doesn't have to chase or find Tyson and that's just the way he likes it. Joe's huge power, great handspeed and sizzling combination punching hold him in great stead in firefights. He can also get out of the blocks too as blindingly obvious in the Schmeling rematch from which he launched three 1 round title defense KO's in a row. I'm not even saying Joe wins this but his assets and chances are being shockingly understated by quite a few in this thread.
Yes, the outcome can be a surprise, but on this forum, in the hypothetical H2H fantasy matches we discuss, I'm taking into account the most likely outcome, meaning if they fight 100 times what's gonna happen, not the less likely underdog winning by lucky punch scenario.
If you are so confident in your ability to predict the outcome of boxing matches, then there is no need to work for a living!
To illustrate the difference in height, Mike Tyson's 5'10. Here's 5'11 Joe Frazier next to Louis : This content is protected "Roughly the same height"
Yes there is. Unfortunately, we do not have a time machine to bring back old timers to fight their modern counterparts, otherwise I'd be very rich. It is much more difficult to accurately predict a fight between 2 modern boxers of roughly similar skill level. Also, unlike our fantasy fights on this forum, we cannot rule out the lucky punch scenario.
You seem to be saying that it is harder to predict the outcome of a math between two fighter from the same era, than two fighters from different eras where you have no common points of reference. This strikes me as being a wildly implausible premise.
Yes and no. At some point, the infrastructure supporting boxing becomes rudimentary enough that I'd pick a modern guy under anything close to modern rules. I don't stay up nights wondering whether Wlad could beat Tom Cribb with gloves, for example.
