IMO: - He is never going to pack a huge punch but he has solid cumulative power. I would suggest dropping down weight from 245 lbs down to 220 lbs. If he drops the weight nice and slow, he will be able to retain all his muscle. Losing 20 lbs or so will likely improve his foot speed, improve his stamina and his power will be about the same. - Use a high lead hand. Wardley landed the big right when Huni was getting tired later on and he tried coming in with his lead hand low. In the early rounds, the lead hand was up nice and high. So his lead hand needs to be high all the time and i think losing weight will improve his endurance and allow him to keep his hands high for all 12 rounds.
He needs to work on his power and build muscle mass to become more resilient, his skills are great but his weaknesses are what I mentioned.
He needs to learn how to box on the back foot and not jump head first into the action all the time. Definitely not once he has build up a big lead against a puncher like Wardley.
His fundamentals are excellent, I don't think he is an easy fight for anyone at HW. It's tough to imrpve power and punch resistance as these are related to natural attributes rather than things you can train.
Interesting that Wardley said "He hits pretty well" also mentioning that he puts the punches together which makes him effective. I don't think the power is a big issue.
His flaws are more physical than technical. Huni's chin/power will stop him from beating heavy punchers. If he gets matched up with heavyweights who don't have power/ gas tank he can win.
