Showtime has a mega promotional series planned in advance of the May 4 clash between Floyd Mayweather and Robert Guerrero. 

Forbes estimates Floyd Mayweather's deal with Showtime as being worth more than a $250 million, although network boss Stephen Espinoza would not comment directly on the six-fight package.

Floyd Mayweather on his groundbreaking new deal: "Showtime and CBS, I've got to take my hat off to them. They did a tremendous job and I am happy to be a part of this family."

Robert Guerrero: "I'm a man of faith. I'm a man of God, and I feel that God has put me in this position for a reason: Not to humble the world of boxing, but to humble Floyd Mayweather."

Leonard Ellerbe, the CEO of Floyd Mayweather's promotional company, said: "The business model that we have put into place, in my opinion, will never, ever be duplicated." 

Golden Boy Promotions CEO Richard Schaefer says Floyd Mayweather's move to Showtime ends the days when the network could not compete with rival U.S. cable giant HBO.

Robert Guerrero's promoter believes the rugged welterweight contender will make for a "dangerous" opponent for Floyd Mayweather, whom he meets on May 4 at the MGM Grand in Las Vegas on Showtime Pay Per View.

Floyd Mayweather signed a groundbreaking pay-per-view venture with Showtime and the cable network's parent company, CBS Corporation, staring with a May 4 fight with Robert Guerrero. Under the terms of the deal, Mayweather could fight six times in 30 months.
