Golovkin had 800K viewers on HBO in his last fight. How does that fare against other fighters fighting on a network?
Cotto, definitely. Ward and Kovalev have a chance to stake their claim, although I don't expect their fight will sell especially well. The thing of it is, after Canelo and Pac (and Floyd if he fights again), there aren't any true PPV attractions. And even those guys aren't likely to sell especially well without facing one another or having a stellar dance partner.
