Short shots about the world of professional boxing:

• The issue of whether there will be a fight between Floyd Mayweather Jr. and Manny Pacquiao, who are far, far and away the two best boxers in the world at this stage, sometime later this year will hinge on whether the fighters and their respective negotiators can resolve the thorny issue of Mayweather's demands for random blood and urine testing.

The same demands scuttled talks between the sides in January.

Pacquiao doesn't want to submit to random testing. He believes giving blood too close to the fight will weaken him. Even those on his team agree there is nothing medically to back up Pacquiao's contention, but if Pacquiao believes it will hurt him, it probably will.

So, why doesn't Team Pacquiao get proactive to try to resolve the issue, because it's making Pacquiao look like a fool and as if he's got something to hide.

A member of his team should do a random blood draw from him, as would be done if he were to be tested prior to a potential Mayweather fight, and then have him spar later that day or the next day.

After doing that several times in quick succession, it could be pointed out to Pacquiao that he sparred as he normally does and had no issues, and that giving a small amount of blood would not impact his boxing ability in the least.

It's worth a try, given what is at stake.

• After Mayweather and Shane Mosley both had no problems submitting to the blood and urine draws prior to their bout, which Mayweather won by unanimous decision on Saturday in grand style at the MGM Grand Garden Arena, it makes it harder to stomach Pacquiao's hesitance.

Agree to the tests and make the fight the world is demanding, Manny. Olympic swimming hero Michael Phelps gave blood one day during the 2008 Olympics in Beijing. Later that day, he went out and swam in one of the heats with no problem, then won a gold medal the next day.

• If it will make Pacquiao feel any better, maybe Mayweather can agree in the contract to give blood immediately after the weigh-in.

• Pacquiao's representatives have said that Pacquiao will submit to any testing required by the state athletic commission where a fight is held. If the Nevada Athletic Commission passed a regulation requiring Olympic-style testing, how much do you want to bet that Pacquiao suddenly would want to fight only at Cowboys Stadium in Arlington, Texas?

• Pacquiao's publicist Fred Sternburg, advisor Michael Koncz and promoter Bob Arum have all denied quotes attributed to Pacquiao in a story on a web site in the Philippines in which Pacquiao was alleged to have said he'd agree to random blood and urine testing if there were a 14-day cutoff.

Reporter Ronnie Nathanielsz spoke to Koncz, who had asked Pacquiao about the quote. Koncz told Nathanielsz in a story on BoxingScene.com that Pacquiao not only denied making the quote, but also said he had never heard of the reporter and had done no interviews.

• If Mayweather and Pacquiao can't come to a contract agreement for a fight later this year – and I'm highly skeptical they can – then I propose that Mayweather face middleweight champion Sergio Martinez. It's a risky fight, but Martinez is a top-10 fighter and it would create buzz as Mayweather tried to emulate a Sugar Ray Robinson accomplishment and win both the welterweight title and the middleweight title.

Boxing insiders may like the idea of, say, seeing Mayweather fight Paul Williams at welterweight, but the general public has no clue who Williams is and the fight wouldn't be very big on pay-per-view.

A story in which Mayweather accepted a serious risk and chased one of boxing's most prestigious belts, the middleweight title, while trying to prove his claim of being better than Robinson, would be off-the-charts good.

It would be a risk for Mayweather, as Martinez is a highly gifted man and is the naturally bigger man. Martinez is not only an elite fighter and the holder of a revered title, but he's a good-looking man who was swarmed by women at the MGM Grand Garden Arena on Saturday when he came to watch Mayweather rout Mosley.

He's a former professional cyclist and soccer player who was born in Argentina but lives in Spain. That would bring some international attention to the bout.

If Mayweather can get past Martinez and win the middleweight title, it would put a point on his side of the ledger in his very uphill battle to overtake Robinson.

• Some boxing fans and media have complained that the Mayweather-Mosley fight was boring. That boggles my mind. Mayweather came to fight. He planted his feet and stalked Mosley, as his many critics said he'd never do.

The difference between the Mayweather-Mosley fight and the Pacquiao-Miguel Cotto fight is that Mayweather was much sharper defensively and couldn't be hit the way Cotto hit Pacquiao. It's not fair to penalize Mayweather because he's brilliant defensively.

• I will have Mayweather No. 1 the next time voting for the Yahoo! Sports rankings are conducted, switching places with Pacquiao.

• CompuBox's Bob Canobbio passed along an incredible statistic. Mosley landed just 42 power punches in the bout, far below the welterweight average of 160. But he landed 13 of the 42 in the second round. For the other 11 rounds, Mayweather held Mosley to just 29 power punches connected, an absurdly miniscule average of 2.6 a round.

• Nobody came out of the Mayweather-Mosley fight looking any better than Mosley trainer Naazim Richardson. Richardson handled himself with class before, during and after the fight and should continue to be one of the game's most in-demand trainers.

• In his last three fights – a 10th-round stoppage of Ricky Hatton and decision victories over Juan Manuel Marquez and Mosley – Mayweather has won an astounding 85 of 96 scored rounds.

• Because California has very liberal community property laws and his divorce from his wife Jin isn't finalized, Mosley is likely to keep fighting in the wake of the Mayweather loss because the divorce will almost certainly be extremely expensive.

• There was an unreal array of boxing greats in attendance at the Mayweather-Mosley fight. Among them were former heavyweight champions Muhammad Ali and Mike Tyson and former welterweight champions Sugar Ray Leonard, Thomas Hearns and Roberto Duran.
