I've been subscribing to Gamepass for 7 years now. It's the best thing since sliced bread. 4k crystal clear streaming. All games in the league. You get the broadcast cover, but also a "Game in 40 minutes" truncated feature (just the plays without the dead time), which is useful for watching other teams games, and also the Coaches Film. It's awesome.
Also you get the NFL RedZone, which I watch when not watching a Pats game. Pats often have a afternoon or evening slot, or Monday game, so Sunday 1pm can be NFL Redzone time which jumps between all games live wherever a team is in the red zone. It's great.
Plus you get the NFL Network as well............ which is whatever. But you get access to all NFL Network shows On Demand, which is decent. Shows like A Football Life, Hard Knocks etc.
