In my opinion it is more embarrassing anyways. Griffin was just to slow for Silva and hence got punched in the face, that's normal fighting business. Silva just made it look special, because he is leagues ahead in timing. Sonnen tried to be cool and fell on his butt like a clown, before curling up scared into fetal position.
I don't know about that. Silva was moving his head before Griffin was even throwing strikes when they fought. That's probably worse to me than avoiding one telegraphed crazy spinning back fist.
