nope... your off on points here...
yes, texas has their own network, but they will only have one game on that network, the conference will still be tied to a network (ABC/ESPN almost undoubtedly) as far as the Big Ten(+2) they are still staying with an 8 game conference schedule, much like the Big 12 had.
Noter Dame can still schedule their friends in the Big Ten and play the service academies... along with throwing a few games at other punching bags, don't be mistaken though, anybody in the country would be more than happy to play ND because its a guaranteed sellout...
Noter Dame likes where they are at, and would only join the Big Ten if they are forced to... they have no desire to be in a conference where UT would outshine them...
