Rocky Marciano vs Mike Tyson

he was 18 years old, he fought in heavyweight and lost narrowly to the later Olympic champion, whom he later got his revenge on. You know well that Tyson was one of the best heavyweights in the world at that time, even though he was not even an adult man.

 

Tyson has to get this done inside 6 rounds for me, if not Rocky takes over and wears Mikey boy down, stopping him late on.

 

If the three knockdown rule is in effect, this might end in the first

 

Somewhere between the Marvis Frazier and Mike Spinks result.

 

Tyson the significantly bigger and stronger Man , With a weight advantage of about 30 pound s .
With his lighting fast punching power, catching Rocky before he has a chance to throw a meaningful shot of his own.
The heart of the Man makes him keep getting up but the ref has a heart too, and stops the fight.

 

Tyson was an elite boxer 30 pounds of muscle heavier then Rocky. This is over inside a round. Two vastly different eras. Now if you want to say oh well if Rocky could have used modern training and used steroids he would have been the same size etc then find someone else to debate cause that’s more fantasy then can be analyzed seriously.

 

And would that modern training and PEDs make him any quicker, longer and better balanced?

 

Exactly, of all the matchups between all time greats in the heavyweight division this one has 1st round knockout written all over it.
Rocky has some advantages , grit , determination and conditioning.... but he'll never get to use them.

 

Take possible prime fights. For Spinks Tyson was 218 1/4. For Charles 1st fight Rocky was 187. 31 lbs weight pull. This is why they created the cruiser weight division. Even if you said everything else was even how do you overcome that kind of weight advantage? Rocky had more heart? Heart is great until your knocked unconscious.

 

Mike was famously known as undersized for a HW but as you pointed out he had over 30 lbs! (of mostly muscle) over Rocky. Big size difference with Mike actually being the faster man.
