At least one of the San Diego Chargers home preseasons games is blacked out each yeah, and I don't care because it means that a few thousand people weren't ripped off by paying regular season prices to attend a game that doesn't matter.
Here's the official word from the team:
Per NFL policy, Saturday night’s game between the Chargers and the Dallas Cowboys will not be shown live in Southern California. The game kicks off at 6:00 pm PT at Qualcomm Stadium.
The League’s long-standing policy requires all games not sold out 72 hours prior to kickoff to be blacked out in the local market. This includes all signals within a 75-mile radius of the stadium and those areas whose television signal reaches within that 75-mile zone. The League’s policy affects all telecasts, including cable and satellite.
Nearly 5,600 general tickets remain available at Qualcomm Stadium Gate C, www.Chargers.com, TicketMaster outlets or by calling TicketMaster at 1-800-745-3000. A variety of Club Seats, some of the best locations in the stadium, and a limited number of single-game Luxury Suites also are available. The Chargers’ ticket office is open weekdays 8-5 pm and Saturday starting at 10 am.
So, yeah. Get those illegal streams that I always see you kids talking about (but I've never actually watched....) ready.
