No he needs better boxing. That's his problem, he's boxing based but his boxing hasn't improved while other fighters boxing skills have. He used to be the best boxer in mma, that isn't the case anymore. His style relies heavily on him being the better mma boxer. So he definitely needs to improve his boxing. Work on other stuff, but his boxing has become a weakness for him instead of strength since his boxing combos/patterns has been figured out. Plus he's not a devastating puncher above 145. He tries to use a power punching fighting style, he needs to learn proper power punching from Canelo's team. That and he needs an inside boxing game because that has always been his weakness that he has never addressed because before Dustin exploited it in mma only Floyd Mayweather exploited that weakness in boxing. Nate exploited it a bit in the 2nd fight but wasn't able to get the win off it. Floyd fight was the fight that made it clear he has a weakness boxing on the inside.
