I own a shield and an apple the in the US. Subcribe to PlayStation Vue for American football and futbol. The pain point is some premier league games are on the nbc sports app. I've found it difficult as not all US network channels have ATV apps (yet they're on Fire TV).
What is the best way to stream live futbol in the US?
An IPTV service would be the easiest in my opinion. I don't watch sports, but do watch all the UFC fights this way.
