In 2019 the easiest way to get all those networks is to stick with cable, unfortunately. You can sorta cobble something together using Hulu, Youtube TV, etc. but it gets expensive and you still might be out of luck for football games.
In our house we turned off Comcast and installed an antenna in the attic. I get the NFL and major broadcast networks through the antenna. HBO, Netflix and Amazon Prime come through the Apple TV. Ended up saving a boatload of money, and we only use Comcast for internet now.
If you use Amazon Fire TV, you can get an Amazon “Recast” device. It’s basically a DVR that hooks up to an antenna. Where I live, we can pick up tons of local network channels (NBC, CBS, PBS, etc.). It’s a great supplement to Netflix and the other streaming services.
You can get very affordable, reasonably attractive, nice quality digital antennae these days. No rabbit ears!
We cut cable a few months ago and ZERO regrets. Switched from Comcast to CenturyLink 1gig fiber at the same time (cheap AND faster).
