But Corrales, later knocked out by Mayweather in one of his career-best performances, stopped Garcia in the seventh round. Garcia fought four more times and was retired by 2001 before establishing himself as one of the world's elite trainers several years later.
"We were champions at the same time in '98 and it's something we have to admire and respect that 16 years later he's still world champion," Garcia said. "He came to be the best pound-for-pound fighter in the world. It's amazing."
Although Mayweather (45-0, 26 KOs), of Las Vegas, will still have three more fights remaining on the gargantuan $200 million-plus six-fight deal he signed last year with Showtime/CBS, he is not sure if he will complete the agreement.
Although it would be hard to imagine the fight with the 30-year-old Maidana being his swan song, regardless of the outcome, Mayweather said he does think about calling it a day after Saturday's bout.
"If I feel like walking away, I'll walk away. I want to settle down and get married," Mayweather said. "As I get older I want to settle down and be with my family. I've had enough fun."
Mayweather also sometimes feels the burden of his celebrity, which can be crushing.
"When I sit back sometimes in my bed and I turn on the TV, I look and I [see things and say], 'I miss doing that by myself.' I want to go places by myself. I want to do things by myself," he said. "You think I always want to go to the movie theater and take security? I want to do things by myself sometimes.
"I want to come to the casino by myself and play blackjack by myself. I want to be able to travel. If I have a wife, I want to be able to travel, just me and her. I want to be able to do one-on-one things, but guess what -- it's a gift and a curse."
Even before the Maidana fight was signed, Mayweather had said several times that he planned to retire at the end of the Showtime/CBS contract, which, if he ran the table, would bring him to 49-0.
Of course, one more fight beyond the deal could potentially move him to 50-0. That is a mighty attractive round number.
"Everybody talking about 50-0 and everybody talking about 51-0, but we take one fight at a time," Mayweather said. "Different days I feel different ways."
Make no mistake, Mayweather said he has prepared as hard as always for the assignment against Maidana (35-3, 31 KOs), the powerful brawler from Argentina aiming for the big upset.
"I want him to bring his best, and he may be the first guy to make me dig in my bag of tricks and pull out my A-game," Mayweather said. "Hopefully, he make me pull out my A-game. My whole career all I had to use was a D- and C-game to beat every guy. I never had to use an A-game or a B-game, so we'll just have to wait and see.
"Everybody keeps asking who is going to crack the 'May-Vinci Code.' Everybody's game plan is come straight ahead, keep pressure, hit him on the leg, hit him on the hip, hit him with a low blow. Head-butt him. I still find a way to win. This guy right here is super fast, this guy got a good left hook, this guy got a good right hand, this guy goes to the body good. I still find a way to win. This guy got good defense, this guy got the best jab, this guy throw combinations. I still find a way to win. Saturday, I'll find a way to win."
On one hand, Mayweather said he thinks about retiring, but on the other he said he wants to keep fighting for the sake of his legacy.
