If us fans never get to witness Pac vs Floyd, who's to blame?

We've all read about how Pacman is interested in a fight with Floyd. He himself even went on the record to say so ("After Floyd Mayweather, my job is done") . His trainer Freddie Roach has went on the record, and even Bob Arum made a statement of how he will lower his demand to a 50/50 purse split in order to make the fight easier to make. Floyd on the other hand has used Pac's losses from 1996, 1999, and his decision loss to Eric Morales in 2005 (in which Pac came back and totally demolished Morales in thier next 2 matches) as an excuse to try and discredit Pac. He blatenly ducked and dodged the question during his interview with Brian Kenny by replying with "Al Haymon and Leonard Ellerbe are my advisors, and have done one hell of a job with Floyd Mayweather's career" after Kenny Asked him why not face the winner of Pacman/Marquez. Everytime Floyd is asked about a fight with Pac by reporters, fans, etc... His reply is always "Pac has been KO'd twice before and got outboxed by Eric Morales" So who do u think would be more responsible for this fight not coming off if its never made? Vote.
