As has been stated, Griffin is a unique champion. I first noticed him on TUF season one, during the stair challenge, where he blew past the other fighters. Then, we see him develop skill-wise over the course of the show, then as a fighter, now as a champion.
I care about him primarily because I’ve seen so much of his career. He is an interesting cat, and I will follow his fights for, if nothing else, experiential loyalty.
Silva is a willing and able man of ability who will annihilate all who oppose him.
