After the LA press conference, Mayweather talks to Fight Hub TV. When asked if he is the same guy he was even two years ago:
No, not at all. I’m rusty. Extremely rusty. In the boxing gym I’m not as fast as I used to be… but I tell these young guys [I train with], ‘Remember, you guys are world champions in the boxing gym. I’m the world champion under the lights… It’s all about winning under the lights and making money when it counts’.
And, if he thinks McGregor can go twelve rounds:
He’s young. He can go fifteen rounds…I’m the old man. He’s the young man.
