LOL ESPN? You're joking right? Dude Casamayor/Marquez is on shitty pay per view and Guzman/Campell is on Showtime.
I'm watching the free one The best fight that night will be Bradley-Cherry anyway. JMM-Casamayor has massive stinker potential. Casa's best strategy is to try to manhandle the smaller Marquez, and Marquez's best strategy is to keep him on the outside and counter, which will probably make for an ugly fight. Guzman would be smart not to engage with Campbell, so that fight will probably be meh as well.
JMM-Casa is on PPV. It would be cheaper to subscribe to Showtime for the month than to buy the JMM-Casa PPV.
You are right. Showtime is going to show Guzman/Campbell and HBO Casa/JMM. If they are at different time then I will watch both, I don't even have to pay for Casa/JMM, I watch all PPV events for free at the bar just around the corner.
