Everyone is entitled to their own opinion and I certainly respect yours.
Same here.
Tyson was slow on reflexes. He took punches, that he should have let slip by him. But, he had the punches that could take down an opponent. Rocky Marciano was a great fighter, and undefeated, but man he took some beatings, standing in front of his opponents, fighting toe to toe, and taking every punch his opponents threw at him.
Then consider someone such as Jack Johnson. He was big, strong, had great punching strength, and speed, but he could slip a punch. Fighting him was like fighting a ghost. He was damn hard to hit. He had superior reflexes. Even long after he retired, he'd travel around, and always stop at local gyms, to see what the new talent was doing. He'd take off his jacket, and get into the ring with young guys less than half his age. He'd say "hit me boy." And, they couldn't lay a hand on him. They'd fall all over the ring, and get exhausted, trying to hit him. That's what I call a great boxer. And, I have no doubt that he could have destroyed any MMA guy, who dared to get into the ring with him.
As for wresting skill, does McGregor have any? He seems to box more than anything.
