If you know where to go you can watch any sporting event free online. Stream it to your phone or iPad and Cast it from there to your big screen TV.
That’s true, but not the casting part. I go to sportsurge.net for this, but the NFL has it’s mitts on that too. It won’t let me cast to TV, when I try, some message about NFL licensing comes on. Unless there is a workaround I don’t know about
