I really don't think him losing a match is going to help it might even make it worse coz as i can see JK doesn't care about anything more than boxing it means the world to him so if he loses (which i can't wish doesn't happen) it will make the situation worse and ik everyone wants him to learn the hard way coz of the way he is and acts also losing a match and having a possibility of ending his career will make him only be more mad at everything and most of all on dr.Dan and let's face it whether we like it or not they are going to end up together so why make it more hard
I i would prefer if he was forced into taking a break coz he really couldn't do anything anymore so dr.Dan helps him and he learns he can't carry everything by himself BUT I also know that the author will probably make him loss a match making him be very mad at Dr.Dan and whatnot
