I think some of it may have to do with style over substance in some recent heavily pushed fighters. We see so many guys now who try to set traps for the big finishers or showy shots. More smoke than fire reading headlines and not doing homework completely on investing early to body. Fighting inside doesn't mean just rushing in and setting up shop to work short punches. Watching a guy set up at range and knock on the door before and combined with inside bursts is a real pleasure to watch. Spence does this well. Young Oscar Valdez off of a hurtful jab transitions to inside work quite well. You have a guy like Wilder with tremendous range and snap on the end but honestly looks clueless and vulnerable when it gets choppy in close. It simply comes down to being well rounded and learning to work more, work hard as a fight evolves. Then you have a Santa Cruz who proved to do the opposite from his reputation for free swinging inside volume and turned top notch boxer last out.
