Floyd Mayweather Jr.'s supposed last boxing match is only a few days away and though there is no sure shot way to predict how that fight is going to end, analysts have started firing shots and making early predictions.

Many were not happy when undefeated Floyd Mayweather Jr. pinned Andre Berto as his next, and as he insists, last boxing opponent. But it is still his one and only attempt at making history and matching Rocky Marciano's clean 49-0 slate, which makes the match still something to watch out for.

The stats definitely give most boxing enthusiasts hope that it may not be as boring as most predict it will be. Berto is definitely younger at 31 years old (Mayweather is 38 years old) and has only lost three of his 33 matches and even though Mayweather Jr.'s reach is longer, it is not by much considering his is at 72 inches, while Berto's is at a close 68.5 inches.

But many still point to the many "disadvantages" of pitting the two against each other.

ESPN Sports pointed out that Mayweather, whether or not viewers agree, has proven he is one of the best boxers, not just of this generation but perhaps in all of history. His accuracy percentage is one of the, if not the, highest among today's active fighters. His connect rate is at a high 46 percent and Berto just does not have enough experience to much this number.

Even if the younger boxer brings his A-game to the match, many analysts say that it's Mayweather's game, perhaps by unanimous decision. Bleacher Report says Berto is, at best, a "what if" boxer. He could be great but he had been plagued with too many injuries, which has deeply affected his speed and punching power.

Fortunately, Berto is nothing but optimistic. In an interview with MLive, Berto says his being "young" and "hungry" make him an opponent to be reckoned with.

Mayweather Jr. and Berto face it off in the ring this Sept. 12 at 8 p.m. with telecast on Showtime PPV.
