Honestly . . . that was the kind of fight that can really change a fighter, even for the winner.
Chuck went from being invincible to getting brutally knocked out over and over again. It was pretty tough.Yup . . . that is why the "next" fight after a war is so key, imo. If they take the time to heel, and get things right, then they can likely still do okay. If they don't, like JdS, then it's a pretty sharp decline, because they will just get battered again in their next fight.
I mean, look how quickly Chuck faded after that huge KO loss.
