The Big 10 does NOT want Texas. Texas has destroyed one conference and is bent on destroying another.
Do you actually think Texas would be anther member and have equal rights like all other teams? Or do you think they would want to try and run the conference (which they are used to). They wouldn't want to give up their share of the Longhorn Network, in which other Big 10 members would share equally. In other words, they would want special benefits and the big 10 is not about to do that. We've seen what special benefits have done to the Big 12. That should be all the lesson that the Big 10 needs.
Same with Notre Dame. If the Big 10 lets one team form its own network and keep all the proceeds, it will destroy the conference. Pretty soon Michigan and Ohio State and maybe even Penn St have their own networks and no one is sharing anymore.
Those teams either have to join as an equal member or the Big 10 had better not let them join the conference.
