The Big 12 appears to be upset with ESPN.

Pete Thamel of Yahoo Sports reports that the Big 12 sent a “cease and desist” letter to ESPN demanding the network not communicate with the conference’s existing members or any other conference about adding Big 12 programs.

Thamel posted about the letter on his Twitter account:

The Big 12 has sent a “cease and desist” letter to ESPN. The letter demands ESPN end “all actions that may harm the conference and its members and that it not communicate with the Big 12 Conference’s existing members or any NCAA conference regarding the Big 12 conference’s members, possible conference realignment or potential financial incentive or outcomes related to possible conference realignment.”

With the 2021 college football season just around the corner, it’s an interesting strategy for the Big 12 to take this action against ESPN.

Update: The letter has been obtained by Sports Illustrated’s Ross Dellenger.
