I think this is why people are so upset. For $99 for the pay-per-view, and the cost of a new house to see it live, people wanted Hagler-Hearns. They wanted the bloodbath, the punch fest...
..but that is not the way Mayweather wins, and it never has been. This was actually a pretty active fight for Floyd. In his last two fights he threw a combined 301 jabs, winning both by decision.
In this fight he threw 267 jabs to win by decision, about 100 more than he's averaged recently.
It was a great fight fought by two very smart, very seasoned fighters, who weren't about to step into a donnybrook. But it certainly didn't appeal to the people who haven't seen many Mayweather fights up til now.
