I like Mayhem Miller perosnally, i think that dudes abosolutly nuts.
Krazy Horse is cool, but he doesn't really push the fights that much he just kinda lays back and counter punches.
Another one is probably Genki Sudo and Chris Leben, Sudo...just because he's sudo and hes absolutly nuts. Leben because he push's every fight and loves to brawl.
What is it that is going to be on your mind when you're on your death bed? Will it be the tedious years of 9 to 5, or the memory of some great acheivement. Maybe a moment you stood in glory to the applause of millions.
