Need the App and internet connection.
I was tired of trying to watch these games (and other Irish sports) on my phone - now I can watch on a big screen. $300 I spent worth it.
I know there are other ways to do this (I have used chromecast), other streaming devices and PCs, but this makes it simple and quick. Plus I can go back and watch replays
I usually miracast(screen mirroring) with my smart phone to my TV it's pretty good. I think anything that has the ESPN App works, Sling TV I think has that as well.
