“There is some rigidity at BYU in terms of what they will and won’t do,” Tulsa World columnist Dave Sittler wrote, quoting a Big 12 source. “Some of it has to do with [LDS Church] rules, and also the way they engage with media partners.”

"In addition the report also says that BYU wanted assurances that an unspecified minimum of the school's games would be televised nationally, and it also wanted the ability to show BYU games that weren't picked up by Fox or ESPN on BYUtv."

"The Cougars also were said to want permission to show their football games not picked up by Big 12 television partners on their own television network, BYUtv, which is available in more than 60 million homes nationwide."

TV was discussed. BYU wasn't talking with the Big 12 for weeks on end about Sunday play only.
