Floyd Mayweather Sr., father and co-trainer of WBC welterweight king Floyd Mayweather Jr. (44-0, 26KOs), does not have a high opinion of WBA welterweight champion Adrien Broner (27-0, 24KOs). Experts often compare Mayweather and Broner, because of their in-ring styles and very talkative personalities. The two fighters, who are friendly with each other, are both managed by Al Haymon.

"Floyd would beat the sh*t out of Broner, beat the hell out of him. I seen a guy standing this damn tall, up to your damn shoulders, give him hell. That's not even a challenge," Mayweather Sr. said.

Mayweather returns on September 14th against Saul "Canelo" Alvarez, and Broner has a return date of November 9th - likely against Marcos Maidana. Both fights will take place at the MGM Grand in Las Vegas, with Showtime Pay-Per-View handling the broadcasts.
