For the second time in a month, the Pac-12 sent an open letter to fans slamming Direct TV's inability to reach a distribution deal with the conference.

The league has yet to reach a deal with Direct TV — or Charter Cable, AT&T or Verizon — to carry the league-owned Pac-12 Networks, which were launched before the football season began.

In the letter, the Pac-12 claims that "DirecTV is failing its customers and betraying its promise to be the sports leader."

The letter says fans will miss out on 20 more football games and 150 men's basketball contests. It encourages fans to switch from Direct TV.
