The best thing to do is pick a TV streaming service, but if you don't want to pay, then manually install Kodi and add super repo for free streaming apps. With the free streaming comes frustration with unreliable streaming sources.
Watching the Ags is easy, any plan that carries the SEC network will carry the games on WatchESPN. The stros and rockets are a bit harder since you have to deal with blackouts and whatnot. That's where the bootleg streaming comes in. Those sites will literally **** on anything without an adblocker installed.
