I sound like a broken record; If you have high speed internet, you can see every SNY game on ESPN3, and maybe ESPN3+, not sure how that will play out this year. You can either watch games on a PC or laptop or use a Rolu or other streaming device and watch it on TV.
Better yet, don't get any cable tv. I haven't had it for 5 years, my antennae gets all the national networks, and my internet can stream whatever I want. Last year using my Roku, I subscribed to Sling, but then dropped it in favor of 39.95+ Hulu plus because they had CBS Sports and 50 sports channels. Only kept it for 2 months, you activate and disconnect online, no arguments with CSR.
We don't miss cable, my fingers were hurting from trying to find something actually good to watch or muting all the commercials. Same problems with Sling or Hulu+, but a lot cheaper! My antennae gets 6 PBS stations (Central Florida), my antennae is 6 foot high in my screen room.
If you do not know how to set up a streaming device (Roku, Amazon Fire, etc) Do a Google search, it is very easy.
