Mayweather won a boxing match that was as compelling as watching paint dry. I don'rt think Pacquiao did enough to win, but Mayweather won because of his ability to frustrate his opponents. Pacquiao needed to win the last 2 rounds big or simply win the last 4 rounds, but Mayweather was slippery.
It was as boring a fight as you can get from 2 world-class athletes with tactical minds. In the beginning I thought Mayweather was breathing through his mouth and that conditioning would be important. He was frustrated that his counters were not working. Then came the middle rounds and Pacquiao looked disinterested or tired. In the championship third of the fight Ii thought Pacquiao would turn it on after getting a second wind, but Mayweather did what he does best - run. Run to another victory.
I wouldn't pay 2 cents to see another Mayweather fight. His like Pete Whittaker and Roy Jones - fight not to get hit.
