Sometimes trainers can reign that focus in. Look at Tyson with Cus & Rooney vs with anyone else. He wasn't injured, he just fought a stupid fight because he thought he was invincible. Give up height, give up reach, give counter punching opportunities galore...yeah he gave up all his advantages and Ruiz wasn't just there to lie down and this is what happens.
Train right, use height, reach, control distance and pace, tie up when hurt, and this isn't an issue at all
