Tell me how Max is supposed to successfully implement his style on Conor when Conor is the better striker, who wants his opponents to come at him and so will pressure Max into trying to do just that and will make him pay with his greater power and accuracy, just like he did then?
Max got better at his style. He didn't reinvent himself a new style. The problem, as it was back then, is his style plays into Conor's hands. You have to hope Conor gasses himself out beating Max to the punch, not Max being better. That's always a terrible idea.
Also, Max is currently on a 12 fight win streak since that loss. 4/12 of those wins came within a year of that loss to Conor. He was the bad fighter you want to pretend he was.
