Missouri would have added a lot more tv sets than Nebraska. And they flat out turned Missouri down. It wasn't an either or situation, they could have taken both of them. They obviously didn't care about Missouri's tv sets. By the way, TCY is in a MUCH bigger tv market (Dallas) than Nebraska, and their football program has been a lot better than Nebraska's recently too. To say TCU adds none of that is completely false.
The Big 12 doesn't care about A&M leaving?!?! lol, maybe you haven't been paying attention, but the Big 12 is on the verge of collapsing if A&M leaves. The reason we are talking about 16 team super conferences is because the Big 12 is expected to collapse if A&M leaves.
First of all, nobody is elevating TCU at this point. In fact, even though it is rumored that TCU is at the top of the Big 12's wish list, it is also rumored that TCU would decline an invitation. Why? Because TCU is already in a BCS conference. Not only that, but TCU is in a BCS conference without Texas demanding to be the supreme ruler, and without rumors that it is on the verge of collapse. I don't know what makes you think they would be elevating TCU and forced to compete on a level playing field, but the fact of the matter is TCU is already there, and would probably decline their offer. You ask why would the Big 12 share millions of dollars with TCU? The simple answer is because they are on the verge of collapsing if Texas A&M leaves. TCU is in roughly the same market as A&M, used to play in the same conference with these guys (and was pretty close to being in the Big 12 before), has historic rivalries with these guys (they are still considered Baylor's biggest rival and they play every year), and has a better football program than A&M anyway. This is the logical choice to anyone who can get past the flawed tv market argument.
Larry Scott? You mean the same Larry Scott that was willing to take Texas A&M even though he already had Texas? I can guarantee you Larry Scott would be all over TCU right now if he was the commissioner of the Big 12. And Beebe has already been rumored to be all over TCU anyway. Seriously, your argument appears to be that it is better to have nobody at all than it is to have the Dallas market (huge) replace the College Station market (which is pretty close to Austin anyway, where Texas is). Why? Because Dallas happens to be in the state of Texas (but nowhere near Austin)? It doesn't make any sense. And it will be funny to see your reaction when it comes to light that TCU has been invited to the Big 12.
