I would have been surprised if we got a notice that said "we will leave for the SEC in 202x"... This is kind of what I expected.
I think the goal for tex/ou is to say "hey, we are available, come and get us" and see who comes up with the best offer. Also, I assume the real risk OU/Tex see is not short term, but longer term when paying players becomes reality (I think just matter of when not if). Not saying they won't go to the SEC, but I think this is one potential option. They don't want to be locked up until 2030 in a new GOR deal that is no longer competitive (currently media rights in B12 are very competitive with other P5 conf)... they want to have the option to leave at any point. Could still leave early, but not necessarily immediately. I am also curious if the major conf teams (from all conf) start to end their GOR deals and attempt a conf made up of top 20-24 brands in the sport.
Ideal scenario for B12 teams is for OU, Tex, and ND to go to 3 different conferences and each take another B12 team as a partner. Some examples:
ND + ISU to ACC
OU+OSU to B10
Tex + TT to SEC (just an example, switch teams / conf as you wish)
Point is, the more distributed the brand names are the more likely an add on could go with them....
I think the potential of both OU and Tex going to the SEC is a threat to acc/b10/pac and meant to push them to action to better evaluate the options. I guess we will see in the days, weeks ahead... but I think Tx, OU are trying to position themselves for flexibility more then locking themselves to any specific conference quickly.
