Bullshit. Read my post about kickboxers. 1 headkick and hes done. Youtube kickboxing heavbyweight champ vs boxing heavyweight champ, ended with the first kick thrown, boxer gave up when he realised his SHITTY DEFENSE only works against men that agree to throw fists in a very specific manner.
I'd much rather be a dude that can throw very good knees, very good kicks, and veyr good punches, than a dude that can throw awesome punches, because the dude that throws awesome punches is open to so many angles and attacks. 1 headkick and he is done. Just like what happeend to that cuck boxing champ.
