Cowboy hasn't been doing great lately and has dropped his striking coach. When I was playing sports at school I learnt that just because something didn't go your way doesn't mean you need to change everything, or anything. You make changes where you think you can improve. Quite often fighters who have simply hit their ceiling or are on the downslope of their careers will change camp to try to shake things up. But in fact their camp was fine and they don't get any better at their new one. Frank Mir and Bigfoot Silva being two obvious examples. What are some times where one camp just wasn't getting the best out of a fighter and he or she moved to a new one and it just clicked and they did really improve?
