Neither really intends to leave.. both are bluffing to secure either more money or more security.
Oregon and UW would leave if big10 invited, but big 10 is not going to invite (not now)
Colorado would leave if it wanted to, but it doesn’t want to. It would rather stay if it can squeeze Oregon and UW for security
Doesn’t mean they won’t leave. CU is probably most likely to leave but I don’t think it’s nearly as close to a done deal as most on CB and the Big 12 media and influencers
