My grandmother gave me one piece of advice before she died. She said, “don’t trust a boxer or a rapper when they say they’re retiring.” Well, grammy, you were right again. Floyd Mayweather Jr. announced his comeback, just a year after his “retirement.”

Money Mayweather, always the shrewd businessman, honed in on the one weekend people are paying attention to boxing to hold his press conference. He claims he’s returning to reclaim his throne, but the real reason is a little less romantic.

In January it came out that Mayweather owed more than $6 million in back taxes. If you’re really good at boxing, and not particularly good at anything else, then maybe it pays to step back into the ring for another big payday or two.

Of course, to hear him tell it, it’s all about pride.

“I don’t have to tell you guys what I’m going to do. You already know what I’m going to do. Ain’t no smaller man going to retire me. How am I not the king when nobody’s taken my throne?”

Unclear is whether that smaller man is Oscar De La Hoya, with whom negotiations collapsed leading to Pretty Boy’s retirement, or Manny Pacquiao, who’s taken over as pound-for-pound champ in Mayweather’s absence.

Pacquiao takes on Ricky Hatton tonight, and the winner becomes the favorite to challenge the winner of Mayweather and Juan Manuel Marquez in July. And just like that, the welterweight division just became the most exciting in boxing.
