It would be a ****ing massacre. Kid Dynamite would literally send Moses's senses into orbit and for them to never return the same again.
If Itauma made it to the second round, I'd consider that a success. He'd be forced to fight backing up against a lightning quick, unusual, moving target and get absolutely slaughtered.
You could argue that Buster Douglas did something very similar to Tyson that Hrgovic did to Moses. I'd still have to go with Tyson though. Too much educated ferocity backed with lethal power, speed and proven gas tank early in his career.
Even worse, no? I think Itauma is an incredible talent still, the highest shelf possible, just didn't condition and/or pace himself properly. If he continues and corrects mistakes, he might still become one of the GOATS.
