Whittaker has knocked the head off jacare and brunson with his right boot. Also beat romero with his effective front kicks. Rockhold has body kicked and finished costas and head kicked bisping which led to the choke I may have forgotten others but thats all i can remember right now. Also to note, rockhold had been head kicked and finished. There is no comparison as to who is the more dangerous kicker. The arguement could be made that rockholds kicks are more effective for setups but i reckon whittakers kicks are even more so, especially his front kick that send his opponents flying back making them reset constantly. Dont be surprised if whittaker finishes rockhold with a football punt to the chops or an axe kick to the cranium.
