If I could hit him then I could hurt him.

I'm 6 foot, 175 lbs and have sparred hundreds of rounds and had 3 boxing "smokers", or unauthorized matches.

I've sparred a fair amount of professional MMA fighters, including one who is now fighting in the UFC at featherweight since the WEC just merged into the UFC.

The featherweight being 135 lbs never hurt me but he was very fast and got the better of me in sparring a couple of rounds.

Admittedly I've never sparred anyone even close to as talented as Calderon.

But I honestly do not think a 5 foot 108 lb man could hurt me, unless I absolutely fatigued myself and then I'd be screwed.

Problem is I'm not sure I could hit the man. I most likely could not.
