Floyd Mayweather Jr. kept it brief, but pointed during his post weigh-in interview.
"I fought every different style you can possibly fight," Mayweather touted before his bout with Logan Paul. "Height don't win fights. Weight don't win fights. Fighting wins fights at the end of the day. And I can fight."
Paul opted to be outrageous, instead.
"(Sunday), I break the f—ing simulation and beat the greatest boxer in the history of the planet," Paul said. "I'm going to get it done. It's a fight. Anything can happen. Floyd is not ready. That's all I can say."
The parting shots put a wrap to an eventful buildup toward the highly-anticipated exhibition bout Sunday night between the boxing legend and YouTuber.
