If boxing matches are like holidays, then Mayweather facing Manny Pacquiao was like Christmas (you know, that Christmas where you had high hopes for potential gifts and didn't get anything you wanted).

Mayweather facing Berto? It sure seems like the Arbor Day of boxing matches. 

The complaints are nothing new for Mayweather, who has been accused in the past of facing inferior opponents in order to preserve his most lucrative selling point: his undefeated record. But the choice of Berto seems particularly egregious, as not only is this the fight that will potentially tie Mayweather at 49-0 with Rocky Marciano, but this also could be his final bout.

And with far more worthy contenders available—cough, cough, Amir Khan, cough—it's hard to find a reason to defend the choice of Berto, who is 3-3 in his past six bouts and simply isn't anywhere close to the level of Mayweather. 

Of course, Mayweather has gone so far as to defend his opponent's merits to promote the fight, perhaps the most telling sign that this matchup doesn't exactly excite fans.

"Berto is a tough competitor, a former world champion and every time he goes out there, he gives it 100 percent," he said, per Dan Rafael of ESPN. He also noted that, "Berto is a very tough guy, he's hungry and he's not going to lie down" and, "Berto is going to push Floyd Mayweather to the limit."

Nobody is going to question Berto's toughness or heart. He fights for a living, after all. But the notion that he'll push Mayweather to the limit? You don't need to be a boxing expert to scoff at that.

Nonetheless, Mayweather will be facing Berto whether the vast majority of the public likes it or not. And like most opponents he faces, he'll likely take a technical approach, using his elite speed and defense to evade Berto's advances, keep him at bay and take his opportunity to score points with his quick jabs and hooks to win another technically impressive but somewhat-boring fight. 

Mayweather doesn't need to knock out Berto to keep his legacy intact. He doesn't need to provide an exciting fight or thrill the fans. He simply needs to win. And like he's done 48 times before, that's exactly what he'll do.
