"Kaepernick need to get the starting job," Mayweather said. "That's what he needs to focus on. I can't knock him. If that's what he believes in and people want to stand by him, then so be it. He got the number one selling jersey, so it's obvious he doing something right."
Mayweather also spoke about race relations in general.
"I'm here to say all lives matter," he said. "A lot of times we get stuck, and we are followers. You hear one person say, 'Black lives matter' or 'blue lives matter.' All lives matter."
Mayweather used his boxing experience to explain his perspective.
"I learned from boxing — what everyone can take in real life — is follow directions and follow order. Don't give nobody a hard time. When someone break in your house, when someone break in your car, the first thing you do is call the police. With me being a fighter, and my hands being registered, if I hit a guy for breaking in my house or break in my car, it's going to cost me more money. So I have to work smarter not harder. I'm gonna call the cops."
"It's not right what's going on within this world on both sides. I think we need to communicate better, we need follow direction. It's rules and regulations to everything," Mayweather said.
