#4 Diego Sanchez
Diego Sanchez has been a part of the UFC for over 12 years now and in that time he's had some of the best fights in the history of mixed martial arts. His warrior mentality has led to some of the craziest bouts that we've ever since and one thing remained the same throughout all of those contests - his desire. No matter what the situation was, he just never gave up.
There have been points where Sanchez honestly looked like he could barely stand, and yet he would rise as if from the dead to pound his opponent with a string of shots from out of nowhere. His career may be winding down now, but nobody can deny how much heart Diego has. Who knows, maybe his determination will lead him to one more push for the title.
