Are Pac and Arum even waiting for Mayweather's response?

I know there was a so called deadline for Floyd to respond. So far, there's been no response from Mayweather. He hasn't accepted nor rejected the contract yet. But why is Arum and Team Pac already looking into Cotto 2 or Margarito. Seriously, they are already taking about potential places like Mexico or the Middle East since Margarito can't get licensed here. Arum wants the public to believe that Floyd is the priority and Cotto and Margarito are the back up plans. From the news I read, it seems more like Cotto 2 is the plan and Margarito is the back up plan. Arum wants to keep it in the family, and Manny seems willing to fighting anyone, but is never specific on who he really wants to fight. Lately, it seems like Roach is the only one interested in Floyd. I have a feeling Arum proposed a shitty contract for Mayweather. So when Floyd turns it down, Arum can turn around and say "Floyd's ducking" and now Pac will fight a real fighter (one of Arum's boys of course), and try to sell it to us as being bigger than Mayweather vs. Pac, like he did with the first Pac-Cotto fight.
