I have streamed games in past years, but recently I have installed an antenna. If you're serious about being a cord-cutter, it's a must.
If you have two or more of ABC, CBS, NBC and Fox, you get a good selection of sports programming in all seasons. The picture and sound quality is also unbeatable on the primary care so if you are having fights with your spouse over speakers, get a damn antenna!
Lots of people think it will be a hassle. I live on a farm that is 50 miles from the city I point my antenna to; it's a $60 antenna on the edge of the roof which I was able to mount without standing on a ladder. I get about 20 channels.
My mother-in-law lives in an apartment on the outskirts of a different, smaller city and has an pair of rabbit ears and gets about the same number of channels. In fact there is one powerful station I can get at my house with an indoor antenna.
Note that those "flat panel" antennas and other odd-shaped antennas you see advertised today are a real improvement over the old rabbit ears and log-periodic antennas. New TV antennas are based on fractal geometry and take up less than half the space of equivalent performing old antennas at the cost of using more wire.
If you remember Broadcast TV from the 1980s or 1990s, today it is better than it has ever been, so there is no reason not to try it out.
