To echo just about everyone else: Not live, don't care.
As someone who is a cord-cutter and has no problem streaming over my 100Mbps line, it really irritates me that I have to watch NFL games over the air. The house I bought came with a giant antenna in the attic (and it's fairly new which is weird). It's like 15 ft long, and yet this thing can't pick up CBS which hosts the majority of Chiefs games, and FOX can be really tricky. That's what happens when you have a few big hills between you and the station and your house is in a small valley. Drives me crazy.
Two years ago I bought the $99 Madden/Sunday Ticket combo deal. After buying it I was really disappointed that Columbia, MO is considered blackout for KC. Then what's the point of the app? Do people really care that much about teams that aren't their home team? I guess people who move, but still, they would be in the minority. I just don't have time to watch that many games. I'd gladly pay $99/season just for Chiefs content. I was able to get around it sometimes by starting the game on LTE and then switching to WiFi. I think with LTE it thought I was in the St. Louis market since we're pretty much dead center between the two. It was still really annoying and if the stream dropped I'd have to mess with it a bunch to get it going again. At some point towards the end of the season it just seemed to not work at all.
Last season I just skipped watching NFL football for the first time since 3rd grade. I watched some Mizzou games and got some press passes to go down on the field and shoot some photos for a couple games. It's just too much of a hassle to stream. That and I was still pissed about the most epic post season collapse in NFL history against the Colts from the season before (is it too much to ask for one playoff win since I was a kid?). Anyway, sometimes I would have to try to find a pirate stream online and the quality was always terrible and it would often glitch out or have ads popover like crazy if I would AirPlay from my Mac to the Apple TV. Ironically I was able to watch the Royals in the postseason just fine on my iPad. So the one year I don't watch the Chiefs the Royals were tearing it up. Hah. I want to watch NFL games again this year but I have no idea what to do. Guess I'll just have to hope the Royals keep it going so I can be entertained…even though football is way better.
