Irrefutable that a heavyweight beats a flyweight. That is not irrefutable. If we took the greatest flyweight of all time and put him in with Marciano in his pro debut I am entirely confident that the flyweight would win.
Yes, obviously it should be stipulated that the fighters be of a similar class. I'll stipulate that now: they should be fighters of the same class. If two fighters of the same class, styles and physical gifts meet, one weighing 176lbs and the other weighing 250lbs, which would you pick?
Because I am more than aware that if we put a flyweight champ in with a heavyweight champ. The heavyweight will win even if his skills are inferior p4p. Also, this thread started because I was tired of hearing that Dempsey and Louis would get blown out by mediocre contenders of today based purely on the fact that they were smaller. At heavyweight size becomes less of a factor. 10 lbs at middleweight means a lot more than 10 lbs at heavyweight.
I refuse the quastion. Hand speed is equal, foot speed is equal, head movement speed is equal, punching power is equal, fighting style is equal, technique is equal. That is unrealistic because in boxing things are never equal. Two fighters never punch with the same power, never have the same speed, never specialize in the same punches, never have the same chin, never THINK the same, never move the same. It is literally impossible for two fighters to have the same punching power yet punch with the same technique and speed yet weigh differently.
There is something in this, because of diminishing returns on power. However, the history of the HW division actually gives more scope for size to matter. Maricano would be giving up an enormous 35% of his own bodyweight to Lewis. For some, this is insurmountable. Your middleweight would be giving up 6% of his bodyweight.
Quote the rest of my post. I was going to give you an answer but I realized in my explanation that it didn't make sense that all things would be equal. It is literally impossible. I don't have time to **** with impossibilities.
