For years the top Boxing networks have been HBO and Showtime. These networks always had the top fights. Now its looking like Showtime's tenure as a top Boxing network is coming to an end. Showtime still has Mayweather but for only a couple more fights. They currently have no upcoming fights scheduled for this year. Al Haymon, Golden Boy and Showtime had a close working relationship but that's over now. Golden Boy has begun working with Top Rank. That caused Richard Schaefer to leave Golden Boy. Many of the boxers fighting on Showtime under Golden Boy never had signed agreements with Golden Boy promotions but were signed to Al Haymon. Al Haymon has taken his stable of fighters to NBC. Fights like Thurman-Guerrero, Gracia-Peterson and Broner-Molina which would usually be shown on Showtime will now be shown on NBC. HBO destroyed Showtime in the ratings for non-PPV events in 2014 and have a lot of big stars fighting under their banner. So, the question is, how does Showtime Boxing play out in 2015?
