^^ Yes, even in the Pacquiao fight, his training or at least when he do the his drills, he is somewhat very slow and not that agile. Maybe that's how Thurman's training is, not focusing on the speed but power because he want's to try to knockout his opponent, and even before he was knock down or lost the fight to Manny, he is known to have that punching power.
So there's no difference it training at all for him, but I think he is more faster that Ugas that Spence recently beat. But has more power behind it. He had Manny in trouble in the later rounds, it's that his weakness was a body punch and when Manny hit him in the stomach, he somewhat wince, meaning he is affected.
I understand what you are saying, I know that some boxers focus on training to their highest potential, in this case it is as you say they want to focus on having more power from the punches, but there are many vulnerabilities when a boxer focuses only on one strategy, if he does not achieve to make a knockout you have to appeal to another plan, but what really fails here is that if you prepare only to knock out you have to get rid of the resistance and from the way you say it, I think neither the time nor the body will reach you You will be able to resist a training so focused on two things, you also have to do things with your diet, it is very different to train for both things, and come out well.
Well, I think many of us know that Spence took this fight as a way to leave Crawford behind and give another view of what his fight could be, here he showed that he will fight Crawford whenever he wants, and I think that for now he can give himself This luxury, I know that Thurman is a boxer who can talk too much, but when he finds himself in the ring with Spence, even if he has said what he has said, if he doesn't know how to do it, I think he will fall, for me there is nothing else, of course. It must be taken into account that in boxing anything can happen and Thurman can obviously win, but to be honest, I see it as very difficult, especially with all the speculations that have been given.
