Anyone remember Mayweather Marquez? Yes it was in 2009, but Marquez paid for every tiny mistake he even thought of making. That's the advantage of being the bigger man.
If they was even remotely close in size (he and Floyd) Floyd would have stopped him brutally in 4-5 rounds Gatti style. McGregor having much longer monkey arms allowed him to make more mistakes without being punished and his sized and weight advantage allowed him to absorb more punishment.
Conor vs Same sized opponent in boxing ring , e.g Golovkin. = 1-2 round job.
