First would be a win by Pacquiao.
Judges’ decision favoring Pacquiao would mean that the fight is lopsided in his favor as Mayweather is perceived to benefit from the usual hometown decision that is prevalent in the sport. In this situation, Mayweather would likely demand that a rematch takes place immediately.
If the fans enjoyed watching the fight, the promoters would just be eager to do a rematch probably on a 50-50 purse split.
Pacquiao’s promoter Bob Arum would likely insist that sharing of the fight purse should now be in Pacquiao’s favor but knowing Mayweather’s recent “A-Side” spiel, he probably won’t settle for anything less than 50-50 split.
The second situation would be a draw verdict, which normally leads to a rematch to determine who indeed is the better fighter between them.
In this scenario, Mayweather would likely insist that the sharing would remain at 60-40- in his favor but depending on their performance in the ring, the previously agreed purse sharing may be altered.
Another scenario would be a highly controversial verdict favoring Mayweather similar to the first fight between Pacquiao and Timothy Bradley in 2012.
In this particular situation, a rematch would still be possible as fans would demand that they face each other again to validate his questionable victory.
There are indications that the fight could result in a trilogy to highlight the opening of the expanded MGM Grand Garden Arena which can accommodate bigger crowd and slated to open to the public next year.
The new MGM facility (MGM-AEG Arena) can accommodate 20,000 people for a boxing event.
Less than a week after the official announcement of the fight, oddsmakers point to Mayweather as the likely winner in the May 2 showdown at the MGM Grand. But the current 2-1 ratio favoring Mayweather could change as the fight draws near.
