Oddsmakers consider Floyd Mayweather to be a heavy favorite against Robert Guerrero, and it looks like athletes and celebrities agree.

In a press release sent out by Mayweather's PR firm, all 19 athletes weighing in picked Mayweather, while 11 out of 14 entertainers also picked the undefeated 36-year-old.

While some of the celebrities did not exactly give detailed predictions -- how much insight does Justin Bieber's "I've got Floyd all day" response really offer? -- others clearly showed that they followed the sport, including Foo Fighters guitarist Chris Shiflett.

“I think Mayweather is WAY overrated," Shiflett said. "Look at his record. Every elite fighter he’s ever been in there with was shot except Victor Ortiz (who was giving him problems until the whole thing melted down). De La Hoya was handling Mayweather with the jab. Mosley almost knocked him out. Cotto was winning that fight but gassed out because he’s shot. Everybody else Mayweather has faced was a bum. Guerrero is young, fresh and motivated. I don't think he’s going to let Mayweather get in his head or be overwhelmed by the moment. The Ghost by decision.”

Perhaps the most interesting prediction comes from Las Vegas comedian Sean Cooper, who says that Mayweather might lose on purpose.

“Mayweather needs to hype up the fight he needs to lose," he said. "Money for the Rematch. Guerrero wins!’’

The full list of responses is below.

Kevin Krigger, jockey of Goldencents in the Kentucky Derby: “I’ve seen some of Guerrero’s fights and he didn’t impress me that much. He didn’t look like a guy who could beat Mayweather. It depends on what Mayweather wants to do with him. He might want to use him to prepare for his next fight. Mayweather will win by knockout in the sixth.”

Dion Waiters, Cleveland Cavaliers: “Hardwork and dedication are the keys.  I spent some time with Floyd in Las Vegas last year and he is the hardest-working athlete I’ve ever seen.  I can’t see him losing now or ever.  He wins by fifth-round technical knockout.”
