Mayweather vs Guerrero: Robert Guerrero says pressure is all on Floyd

Robert Guerrero is going into by far the biggest fight of his career tonight against Floyd Mayweather, but says he's not feeling any pressure, though he expects the same is not the case for his opponent:

"The pressure's on him to stay undefeated and keep his legacy. He signed a big contract and he's got a lot of stuff to fulfill. I've dealt with losses and come back so it's not on me, it's on him.

"My focus is on what I've got to do to get the job done in the ring, executing my gameplan and doing what I have to do."

Mayweather's six-fight, $200 million contract with Showtime was huge news in the boxing world earlier this year, with $32 million guaranteed to Mayweather for tonight's bout.

Guerrero, on the other hand, is in what we always talk about with these fights -- a no-lose situation. If he loses tonight, that's what is expected. Mayweather is the heavy betting favorite, and few expect Guerrero to win this fight, many doubting he even poses any serious risk for Floyd.

Will this help Guerrero tonight? Well, it hasn't helped anyone else in any of Mayweather's recent bouts.
