If you have a tablet that you wouldn't mind watching games on, NFL + Premium is only $99/year. Looks like you get pretty much all the games...

I have Hulu+ Live TV - it is $82.99, and also includes Disney+ (with ads) and ESPN's current package (with ads). You can upgrade to no ads on the two streaming services also if you want to. I've had minimal/no issues with the service. It's pricy, but it was the best option that had all the live TV channels we wanted. Still quite a bit lower than what I was paying xFinity for cable TV...

Otherwise, do you live in a major city in Wisconsin? Have you looked at getting an antenna and pulling in your local channels over the air? That would get you most of the way there as long as you could get all four major networks...
