Obviously. I was just pointing out that they've held this for so long that it's strange to let it go considering they still hold the TM to Big 8. My guess is they've determined the value of the Big 12 brand outweighs the stupidity of having more (or less) teams than 12 but why let the TM go is my question. (Not that I expect an answer here to the question.)
Complete speculation, but maybe they realized they never want to have 14 (either 10, 12, or 16), and don't see the value of that name. Keeping Big 8? That is a historical name that the conference wouldn't want to see picked up by someone else and devalued/ruined/confused. There's no history with the big 14, just potential need or value.
