Streaming NFL playoff games

Fellas,

I’m new to the world of smart TV....do any of you stream NFL games ? Is there an app ?

I use an Android Box and pay 25 bucks for IPTV and have more channels then Bell or Rogers can even offer and yes dedicated sports.
Yes you can download apps but frequently they get disabled and you have to find the next one and since I don't watch much TV and it's mostly for wife and kids iot was easier to go with IPTV.
