Anonymous Coward suggested three workarounds for cable-exclusive sports telecasts. They may work for some people but not for others, and here's why:
actually going to the game
Cable is far cheaper per year than season tickets for you and junior to two sports. Attending games in person is also impractical for people who follow an out-of-market team, such as fans who moved away from their favorite team, fans of the team associated with the university that a family member attends, and fans whose favorite player got traded to another team.
or streaming it where available
It probably isn't available. If it's shown OTA or on a national or regional sports network in your area, it's blacked out online.
or going to venues that screen the game.
That depends on how many other people at Buffalo Wild Wings want to watch the same game that you and junior want to watch, and restaurant food is still more expensive than home-cooked food. Or if by "venues" you mean a neighbor's house, that eventually gets ruled out as well.
