He can learn new skills. Ever boxer does. It takes most boxer 30 days to learn the stance, and to throw the three basic punches. They are the jab, right hand, and left hook. You add stuff as you go. Sometimes you pick up stuff from your opponent. I agree with you that his basic style is set, but he can sharpen up his tools. The problem is, he has a white dude there, in his camp, that probably haven't even boxed amateur let alone pro. He is controlling his learning process and his growth. He needs Mark there on a full-time basic so he can develop. Plus, he has to listen. I believe he is enraptured with his power and that all he wants to rely on. Now, he really sees that his power can be neutralize. Either he going to learn from this and grow, or you will see him get his ass beat on a consistent basis. He needs a good hook. All he has is two punches (a jab and a right hand). He also needs, to learn to roll with his right. It is a slip move where you catch your opponent coming in with the straight right. Basically a counter right with some pazzazz on it. As a heavyweight, he needs some body work also. If he would have started on the body of that big mofo, he would have stopped the attack. It would have lessen Fury's power and slowed him down. See, there are some basic shit he is missing because his team don't know. Now, Mark knows. Shit, Mark been up and down through there. He is an Olympic gold medalist and a world champion who got that ass beat also. But his massive experience can help Wilder get better if he is with him all the time. Basically, Mark probably comes in at the end of training camp. That's how the big trainers do it, and that is most likely what Mark is doing. This is a teachable moment for Wilder, either he will learn or he will move out of the way for the next.
