Wish I could find the actual quote, but after being warned, then DQ'd, Frank said something to the effect of (and no exaggeration) "Yeah, I knew I was hitting him in the head with the knees, but I figured he'd move it so he wouldn't get hurt". So yeah, those knees we're perfectly intentional, and pretty vicious.

And the reason they say Frank lost is because while Renzo didn't do a whole lot, Frank essentially did nothing.

I was really rooting for Frank in this one, but he just doesn't look like he used to. I hope he gets back into the game and reclaim some of his former glory...he was always one of my favorites.
