Viagra for Heath Herring! He didn't land a single punch on Brock Lesnar!

This is some serious stuff. We're not talking about the not-exactly-Miguel Cotto body shots that Heath Herring was tagging Brock Lesnar with while he was being smothered. I can't count the number of meaningful punches that Herring hit Lesnar with, because there were none. Nada. Z-E-R-O. I first noticed this during the fight. Then I reviewed the fight footage again to make sure that what I saw was correct. How did this catastrophical, Viagra-requiring impotence happen?
