If a guy throws a lot of straight right leads,just bring ur left hand up high and move it out away from ur face a little bit,example ricardo lopez,u can simple stuff the guys right hand be4 it gets close 2 u,and if he throws it behind a jab u can stuff his right by just jabbing back,either jabbing his glove and stuffing it or hitting him n the chest or face to throw the balance off,and if he start 2 kinda loop it,when u have the hand high and out a little,u can jab out tucking ur chin under ur left shoulder and stop it ala larry holmes he was a master at it
