Not if you are in the local market. I never need anything other than an antenna to watch the Packers. I don't even have a legal path to the Brewers anymore because I got sick of trying to figure out what games would be on or not. I remember a period of swapping between Sling and YouTube and whatever. It sounds like now, that may be easier?
I just follow it on my phone/radio and for the playoffs I will add one month of whatever is easiest. I'm still not really sure what that is.
