Do you believe fighters actually know when they are shot. I use kell brook as an example, do you think when he was sparring that he was getting caught with shots that he wouldn’t normally and that he was maybe getting wobbled or shook by shots that wouldn’t have bothered him in his prime. Surely fighters can tell that their punch resistance has diminished through sparring?
I think in all sports it must be so hard to walk away when you have climbed to the top of the sport you are in! I think Brook and many others egos and competitive nature that got them so much success earlier in there career still think they have it when everyone around them knows they haven’t !
