Once a coward, always a coward.

You would think maybe now, after almost five years of ducking and dodging, after Manny Pacquiao has been knocked out cold, that Floyd Mayweather might finally be open to the idea of participating in the biggest superfight in the history of prizefighting.

Nope. Floyd Mayweather is still terrified of getting in the ring with Manny Pacquiao.

Here's Mayweather's latest excuse which came just days after Pacquiao denigrated Mayweather as "all talk."

"Everybody's like, 'Aw, Pacquiao,' but I'm just letting you know he's not getting a fight with me," an angry Mayweather said to Yahoo Sports this week. "The only way he's getting the fight with me is if he signs with Mayweather Promotions. He's got to give me fights with Mayweather Promotions. If he don't give me no fights under Mayweather Promotions, then he's not getting the fight. That's how it is working now, because the ball is in my court. The ball has been in my court. I have been the A side."

It's just more cowardice from the all time king of cowardice, Floyd Mayweather. With Mayweather, the excuses and reasons to duck Pacquiao never cease. Since late 2009, Floyd has used a multitude of escape hatches to evade Pacquiao, including: All he has to do is call my name...Random drug tests...no Bob Arum...I'm not interested in fighting now, I'm focused on promoting...I'm retired...Pacquiao has to accept $40 million and zero PPV...It's not about money anymore it's about health and being there for my kids, self preservation and not ending up like Muhammad Ali...Pacquiao has to avenge his losses to Bradley and Marquez first...

Whenever it seems the fight might be close to signing or hopefully realistic, Mayweather always comes up with a new condition to kill and cancel the all-time welterweight clash of titans.

Never in over a hundred years has the sport of boxing witnessed one man continously and constantly block the biggest prizefight in history from being made. And never before in boxing history, have we watched the powers-that-be conspire to rescue, protect and reward a coward for his obscenely obvious cowardice. (Hey, he even told us: "But I'm a rich coward!")

The face of boxing in America right now is a coward and a fraud, and in these illogical times, that's what the American powers-that-be are trying to sell to the public: a counterfeit, coward, fraud pretender. You have to worry and wonder what the future holds for boxing in America with these kinds of judgements being made by boxing's decision-makers.

Boxing used to be about true competition, matching the best against the best: Ali vs. Frazier. Leonard vs. Duran, Hearns and Hagler. Bowe vs. Holyfield. Now it's more like WWE, with the promoters manufacturing stars and making the fights they want to produce for their own interests and priorities, the heck with the fans and what they want.

Mayweather knows he's secure with Showtime and Golden Boy and the control-freak megalomaniac Al Haymon watching his back, so he can say or do anything he wants.

A former world champion boxer who is aware of how Haymon operates, describes it like this: "What Al Haymon wants Al Haymon gets. Al Haymon manipulates everything. Such is boxing in 2013."

Once again Mayweather has done his part to deprive the sport of boxing the biggest event in ring history. And once again, boxing has embarrassed itself and mocked the integrity and lofty status that all time warriors like Muhammad Ali, Mike Tyson, Ray Robinson, Ray Leonard, Roberto Duran, Evander Holyfield fought so hard to build up.
