It's cheaper than subscribing to DirecTV and buying NFL-ST, but $350 is still pretty steep for non subscribers. I ditched DTV in 2018. For the past few years, I've used my son's university email address to get the streaming package for $99, which has been nice. He graduated last May, but they auto-renewed without verifying his address, so I got it again last season.
This year, I'll look at the schedule and see how many games I'd need it for. If there are just a few, then I might get the NFL+ package and watch recordings of those games after the fact.
On the other hand, I can afford it, so I might just bite the bullet and pay up.
