probably HBO and Showtime. Bob Arum is working with the CBS CEO but that doesn't mean HBO is working with Showtime. We've never heard from HBO saying that they would work with CBS/SHO and we never heard from CBS/SHO saying they would work with HBO. it's basically speculation. I just don't think HBO and Showtime will come together.
I don't think Pacquaio is exclusive to HBO and Arum can take him to Showtime to face Mayweather...just don't see Arum boxing himself in like that. I also see Arum running a risk of talking backdoor dealings with Moonves and trying to become the A-side of the negotiations that will tank the fight...he's gonna wind up pissing Floyd off by disrespecting Floyd's position as the A-side. Arum doesn't need Moonves to deliver Floyd...Floyd delivered himself May 2nd 2015. I think Arum is trying to get a better split...50/50 for Pacquaio. Latest "talks" not "facts" say Mayweather is offering Manny a 60/40 split. So let's see what happens from there--->
Mayweather to get 0 million, Pacquiao million
