The boxing world hated Floyd Mayweather's final fight

Floyd Mayweather defeated Andre Berto via unanimous decision on Saturday to supposedly retire at 49-0.

Though there's been speculation that Mayweather will still come back for another fight, he insists he's finished, which all in all, has left a bad taste in the mouth of the boxing world.

First, anticipation for this fight was low. Many people hated the matchup, feeling Mayweather only took the fight with Berto, who was heavily outmatched, to finish his career undefeated. ESPN's Dan Rafael wondered if it was a joke; boxer Victor Ortiz called it embarrassing.

When it came to the actual fight, the reviews were less than flattering, as expected.

Dan Rafael praised Mayweather's performance, but didn't make the fight sound exciting, writing, "Berto, the critics said, had no prayer to win. As it turned out, he was not remotely competitive, as Mayweather was razor-sharp."

Mirror's Ben Curtis wrote:

"Berto struggled to land a meaningful punch as Mayweather danced his way to victory, interacting with the crowd mid-round and showboating towards the end. The fight was everything boxing fans feared beforehand as Berto failed to impress the judges and a packed-out audience.

As MMA Fighting's David St. Martin noted, many MMA fights and trainers trashed the fight during the action:

Whether the timing was intentional or not, Manny Pacquiao posted an Instagram around the time of the fight, showing what he does when he's bored:

Others in the boxing world voice their displeasure, too:

Sports Illustrated's Greg Bishop described a "half-empty" theater with a "half-asleep" audience watching the fight. He noted overhearing one woman in attendance ask who Mayweather was fighting, while somebody in front of him fell asleep during the fight.

Though the pay-per-view numbers haven't come in yet, it's reasonable to think that they'll be a disappointment. Four days before the bout with Berto, there were over 2,000 tickets remaining, and they were going for about one-tenth of what tickets for Mayweather-Pacquaio fight cost. The revenue figures will look paltry, especially compared to the record-shattering Mayweather-Pacquaio fight. Wall Street Journal's Gordon Marino noted after the Berto match that "at least Berto won $4 million." While hardly a purse to laugh at, it looks like change compared to the $210 million Mayweather won for fighting Pacquiao. 

Still, despite Mayweather's insistence that he's done boxing, few people think he's actually done. His own father thinks he'll come back, and Pacquiao recently demanded a rematch. While aligning their schedules might be difficult, if Mayweather wants to go 50-0, the allure of an old, injured Pacquiao and another huge payday could be tough to pass up, especially if it means winning back some current critics.
