Here's my list; 1. Bika vs. Codrington 2. Marquez vs. Vasquez II 3. Pavlik vs. Taylor 4. Mayweather vs. Hatton
Other fights might have been better than PBF vs Hatton but that fight was on a big scale and ended in dramatic fashion
As much as I hated the result but so far Pavlik vs Taylor wins it. Pavlik is nearly out early then comes back and wins it, definitely deserves to be fight of the year for the entertainment it brought.
I like Taylor/Pavlik as the winner. If you're talking about best pure action fight, then its probably nothing any of us have heard of its probably some Australian club fighters beating the **** out of each other for 10 rounds.... For my money, the magnitude of the fight matters
