A LOT of people are pissed about spending a $100 on the Mayweather vs. Pacquiao fight. And, to a certain extent, I get it. I'm a huge boxing fan. I think the fight was good (not great) and we were all expecting a fire fight that never happened. Mayweather dominated right out the gate and made Pac Man look like a flailing amateur. But, if heavy hits and knockouts are what you're looking for, check out my list of some of the greatest fights in boxing history.
