Youtube TV. You can get pretty much any sporting event simply by using a spoofer to temporarily change your location to wherever the game is locally.
I watched Steeler games this way, for free, all last year and twice already this year.
But assuming you're in Ohio, YTTV has all the networks and you'll also get BTN and ACCN, for free. They have some other upgrades in 4k packages that I never bothered with.
