Fire up Kodi to find a stream
Known to some as the "black market Netflix," Kodi's a streaming client that cord-cutters have been using to get their content fix for years now. The program runs on Windows, Mac, Android, and iOS, and allows users to easily browse and access free streams of movies, live TV shows, and most importantly, PPV sporting events. The main upside of Kodi is, instead of having to scour the net for this stuff, it's all in one place -- provided you've set it up in advance.
Yes, the downside of Kodi in this instance is it requires a bit of lead time to set up, and it can seem daunting if you're not the least bit tech savvy (even if you download the TVMC custom build with add-ons preinstalled). As a result, this isn't really the best option if you're down to the wire and looking for a last minute streaming option. If that's you, maybe just use one of the previously outlined methods, or bite the bullet and pay for the fight like everyone else?
