Floyd Mayweather Jr.'s victory over Shane Mosley on Saturday at the MGM Grand Garden Arena silenced many, but not nearly all of his critics. In this week's edition of the boxing mailbag, I'll address a slew of issues surrounding the big fight, as well as assess a reader's drug-testing plan that will hopefully get Mayweather into the ring with Manny Pacquiao soon. It's pretty much all Mayweather all the time these days as we delve into the mailbag to see what the readers were thinking.

I am getting tired of getting my boxing news from Yahoo! Sports. There is a constant tirade against boxing and a lot of hoopla for mixed martial arts (the UFC in particular). That starts to make me think there is a hidden agenda here. Martin Rogers writing that the Mayweather-Mosley fight was lackluster when, in my opinion, it was one of the most technically proficient fights in history, is ridiculous. I am one of those that do not consider

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

LAS VEGAS – All of the attributes that have made Floyd Mayweather Jr. one of the elite fighters to have stepped into a boxing ring were on display in his one-sided victory over Shane Mosley on Saturday before a crowd of 15,117 at the MGM Grand Garden Arena.

Mayweather's blistering speed continually made Mosley look like he was stuck in quicksand. He adjusted after getting hurt with a punishing right hand in the second, proving his boxing IQ is second to none.

His legendary defensive skills held Mosley to fewer than 100 punches landed and just a 20 percent connect rate.

Yet it was offense that won the fight for Mayweather. He walked down a man who was touted as too big, too strong and too hard a puncher.

He won 10 rounds on judge Bobby Hoyle's card and took all but the second on the cards of Dave Moretti and Adalaide Byrd. Yahoo! Sports scored it 118-110.

He did it by stalking Mosley and putting on an offensive show that makes it even more

LAS VEGAS – Kevin Iole's scorecard from welterweight Floyd Mayweather Jr.'s unanimous decision victory over "Sugar" Shane Mosley at the MGM Grand Garden Arena. Judges Adalaide Byrd and Dave Moretti scored the fight 119-109 and Bobby Hoyle 118-110.

LAS VEGAS – The greatest fighters often have the loudest and harshest critics. Jack Johnson was derided as cowardly. Muhammad Ali was portrayed as a lunatic. Fans wanted to organize a "Roycott" of Roy Jones Jr.'s fights because they were so upset by the caliber of his opposition.

It can't come as a shock then, that Floyd Mayweather Jr., perhaps the sport's most physically gifted fighter and perhaps its best, has been inundated by criticism about his courage, his opposition and his style.

Mayweather, who is 40-0 with 25 knockouts, has said he doesn't expect to be truly appreciated until 20 years after his final fight.

Mayweather has the opportunity on Saturday, though, to put a halt to much of the talk when he meets Shane Mosley in the year's most significant bout in a 12-round welterweight match at the MGM Grand Garden Arena.

Mosley is the type of opponent that Mayweather's legion of critics have accused him of dodging – a fast, powerful

LAS VEGAS – Their goals are the same, but the motivation for fighting each other on Saturday at the MGM Grand Garden Arena is vastly different for Floyd Mayweather Jr. and Shane Mosley.

Mayweather sneers and snarks at a reporter who asked him about his relationship with his father and his uncle.

"You people are always trying to get into my business," he said. "I'm not looking into your business. Why are you worrying about mine?"

It's not long, though, before Mayweather is volunteering much about his personal life. He tells you how much he's made, and what he believes he potentially could still earn. He boasts about his five homes – "All paid for," he says, proudly – and his fleet of cars.

And he's brutally frank about his reason for climbing into the ring. He is almost incredulous when he learns that Mosley accuses him of fighting just for the money.

"I'm a prizefighter," he said. "A prizefighter. You understand that, right? I'm a

It was a travesty, nearly anyone of substance in boxing agrees, that Floyd Mayweather Jr. failed to win a gold medal in the 1996 Olympics in Atlanta. He was so much more gifted than the rest of the field that it was almost insulting to pull a bronze medal over his head and place it around his neck.

Mayweather's loss to Bulgarian Serafim Todorov conjured up uneasy memories for U.S. boxing fans of the 1988 Olympics in Seoul, Korea, when Roy Jones Jr. was robbed of a one-sided win. Despite his loss, Jones was still voted the most outstanding boxer of those Games.

And it was obvious, despite his loss to Todorov, that Mayweather was the elite talent coming out of the Atlanta Games.

The 1996 Olympics produced a number of quality fighters, including David Reid, Fernando Vargas, Wladimir Klitschko, Vassiliy Jirov, Antonio Tarver, Thomas Ulrich, Oktay Urkal and Daniel Santos.

None of them, though, were nearly as gifted as Mayweather.

He quickly

Richard Schaefer had heard plenty about Saul "Canelo" Alvarez, but he really had no idea what he had when he signed the 19-year-old to a contract with Golden Boy Promotions.

On Sunday, he saw a glimpse of what the future may hold.

Alvarez, an unbeaten teenager who looks like Howdy Doody come to life, made a promotional appearance in Los Angeles on Sunday at Fiesta Broadway, the largest Hispanic festival in the U.S.

Schaefer, the Golden Boy Promotions CEO, could hardly believe the fresh-faced kid he'd met was having such an impact with the crowd.

"I saw him interacting with the people and I'll be honest with you, it was like he was the Mexican James Dean," Schaefer said. "I've never seen anything like it. The looks, the charisma … My wife is Mexican and she felt it and said you could tell this kid is different.

"It's difficult to describe, but you're drawn to him. He's a captivating personality."
