Boxing fans have been waiting for Floyd Mayweather and Manny Pacquiao to step in the ring together for years. Each camp would probably tell a different story about why the superfight hasn't come to fruition, but it has been a missed opportunity for the sport as a whole.
That hasn't stopped Mayweather from delivering a holiday haymaker on Twitter.
The undefeated American posted what he called his "Christmas card to the world" on social media, showing a funny chain of events from back when it seemed like a deal was getting close:
The accuracy of the holiday greeting from Mayweather to his rival is obviously up for debate, but score this round for him regardless. His ability to talk big out of the ring is made possible because he backs it up every time the bell rings.
It's a timely message because the idea of Mayweather and Pacquiao facing off was recently brought back to the forefront after fading away for awhile.
Mayweather has continued to win. Since the middle of 2012, he has scored unanimous-decision victories over Miguel Cotto and Robert Guerrero as well as a majority decision over Saul Alvarez. His record stands at an unblemished 45-0.
Things haven't gone as smooth for Pacquiao. Over that same time frame, he was upset by both Timothy Bradley via a controversial split decision and Juan Manuel Marquez, who delivered the crushing blow that left "Pac-Man" on the mat, as shown in the tweet.
But Pacquiao bounced back to score a convincing unanimous-decision triumph over Brandon Rios, bringing talk of a bout with Mayweather back into the picture.
Judging by the holiday jab, it doesn't seem like the sides are trending in that direction, though. Greg Bishop of the New York Times passed along comments from promoter Bob Arum after Pacquaio's win while also explaining why a deal is unlikely.
"If everybody wants it to happen, it can happen," he said (although that "everybody" would include Arum himself).
"I mean, there’s no impediment," he said (although there are several, most prominently the current cold war between Top Rank and Golden Boy Promotions).
"It’s been done before," he said (and he meant those generational-type fights, not the best fight that can be made of this generation).
A window remains if the two sides want to come together to work out an agreement so the battle can finally take place in the ring instead of on Twitter and through the media. A fight between the two would still generate plenty of hype.
Based on his Christmas card to Pacquiao, however, it doesn't seem like Mayweather is interested.
