Number of blackouts: Four
Ownership wants a new stadium, taxpayers don't want to pay for it. That's what it boils down to in San Diego, where a Chargers team that sold out 48 straight games through 2010 now blacks out home games annually. The Spanos family of owners has threatened to move the team to Escondido, Chula Vista or, more seriously, Los Angeles and has made it clear they'll go wherever they can get a new stadium and a shot at hosting the Super Bowl.
Number of blackouts: One
The other team in the Los Angeles sweepstakes is no stranger to either blackouts or stadium squabbles. The Raiders tried Los Angeles once before, but headed back to Oakland in the mid-1990s. Since then, Raiders fans have dealt with dozens of home-game blackouts that made the Oakland Coliseum a black hole for its stadium of painted crazies and television screens across the area. The Raiders' lease at O.co Coliseum ends next year, which has given management an excuse to go house hunting. The team considered joining the 49ers at their new stadium in Santa Clara and weighed building a stadium in Dublin, Calif. But new owner Mark Davis is invested in Oakland and even accepted the 85% attendance threshold for lockouts.
