According to multiple sources, Texas, after talking to ESPN, has agreed not to air any content involving high school athletics, not even the news-style highlights that had been approved by the NCAA, sources told Orangebloods.com Wednesday night. It's the latest attempt to reach peace in the Big 12 as part of an agreement in principle for schools to grant their Tier 1 and 2 TV rights to the conference for six years. The "compromise" deal was struck Wednesday after Big 12 interim commissioner Chuck Neinas gave Texas a 24-hour deadline to consider the Tier 3 content concessions, which impact Texas the most because of its Longhorn Network, sources said. The question is if this agreement will be enough to keep Missouri in the Big 12.Via Chip Brown at Orangebloods. "SOURCES," etc., but ... interesting.
