Unless Floyd is creating his own cable network, he still needs a network to provide his platform (and Floyd ain't fighting on CBS live anytime soon). Showtime IMO didn't provide the promotion this fight needed to have a return Showtime "assumed" they'd get, even by fighting Robert Guerrero.
To me, I think Showtime's mentality was based on Floyd's track record, he could fight anyone and it'll be a Million PPV buys. If HBO was THAT confident in Floyd based on the list of fights ahead, I think they would've thrown the kitchen sink plus the sponges to Floyd.
That's because NOBODY cares. To the average casual boxing fan, these guys Floyd is fighting are no-names.
Nobody is buying any PPV until, if ever, Floyd fights Pac.
