By Eric Thomas: If you want to any single reason for why Floyd Mayweather Jr. (44-0, 26 KO’s) was willing to agree face the younger, bigger and stronger Saul “Canelo” Alvarez (42-0, 30 KO’s) on September 14th in a pay per view fight in Las Vegas, Nevada, it likely has to do with Mayweather’s PPV numbers from his last fight against Robert “The Ghost” Guerrero on May 4th.
Although the numbers still haven’t been officially released to the boxing public, the word is that they were underwhelming numbers, far fewer than what was expected. That might have pushed Mayweather to agree to the Canelo fight because having his fights bring in less than 1 million PPV buys isn’t a good thing due to his expensive six-fight Showtime/CBS deal.
By Allan Fox: WBA/WBC junior middleweight champion Saul “Canelo” Alvarez (42-0-1, 30 KO’s) and WBC welterweight champion Floyd Mayweather Jr. (44-0, 26 KO’s) have both agreed on a fight on September 14th at a catch-weight of 152 pounds at the MGM Grand in Las Vegas, Nevada. 
By Mo: WBC Welterweight Champion Floyd Mayweather Jr. is indeed a great boxer and has undoubtedly the best defensive style of our era, yet he keeps fighting the wrong boxers and the big fights that the fans would love to see never get made. 
By Dan Ambrose: 22-year-old Saul “Canelo” Alvarez is showing his youth with his all thumbs approach to getting an import career-changing fight with Floyd Mayweather Jr. Canelo, despite being at the beginning stages of his career, is telling Mayweather at what weight their fight has to take place at before agrees to it.
By Juan dela Cruz: Just recently, Floyd Mayweather Jr. said that he will fight Saul Alvarez but the bout has to be at 147-pound limit (welterweight). On the other hand, Saul Alvarez said the fight has to be at 154 pounds (Jr middle weight). With this, the fight seems unlikely to happen. But who’s to blame?
By Dan Ambrose: WBA/WBC junior middleweight champion Saul “Canelo” Alvarez (42-0-1, 30 KO’s) appears to have drawn a line in the sand in terms of the weight he’ll agree to fight Floyd Mayweather Jr. (44-0, 26 KO’s) on September 14th by saying he won’t go below 154 to fight him.
By Dominic Sauboorah: WBC Welterweight champion Floyd Mayweather (44-0, 26 KO’s) has recently stated how he will only fight Saul Alvarez (43-0 31 KO’s) at the 147 lb. limit and not Alvarez’s natural weight of 154 lb. That’s unlikely to happen, considering that Alvarez is naturally a middleweight so it’d take a lot out of his body if he were to drain down to 147 lb. We’ve seen the effect that’s had on fighters on the past, like Oscar De La Hoya when he fought Manny Pacquiao.
By Tom Drury: The drums are banging for a Floyd Mayweather Jr. vs. Saul “Canelo” Alvarez match-up for September 14th. These two men are arguably the biggest stars in boxing. However, Alvarez still has to cement his status as one of the best fighters on the planet. Firstly, I would like to say I was a critic of Alvarez due to his padded and weak resume and was one of the first to speak out believing he would be schooled by Austin Trout. 
By Dan Ambrose: Oscar De La Hoya of Golden Boy Promotions says his fighter WBA/WBC junior middleweight champion Saul “Canelo” Alvarez (42-0-1, 30 KO’s) can’t possibly make 147 lbs. even if he wanted to for a big money fight against boxing’s biggest star Floyd Mayweather Jr. (44-0, 26 KO’s) on September 14th. 
By Dan Ambrose: WBA/WBC junior middleweight champion Saul “Canelo” Alvarez (42-0-1, 30 KO’s) is in a bad situation as far as his next fight date goes on September 14th. Canelo absolutely has to fight Floyd Mayweather Jr. on that date because if he doesn’t, he’s going to be bumped from that date by Mayweaher Jr.
