Because of their weak fanbase, their irrelevance with regards to national media attention, their woeful athletic showing in the two revenue sports over the last 20 years, but most importantly the lack of television sets they bring. A&M and Texas bring with them to Dallas, Houston, Austin and San Antonio markets. Again, your views on this subject are narrow and shortsighted and lack any perspective whatsoever. You don't seem to understand how college athletics works in the year 2011. It's about money and TV sets, of which Baylor brings neither. A couple years of incredibly moderate success is irrelevant in the grand scheme of things. Has A&M been great in football over the last decade? No, and yet the SEC still covets them.
And let's not act like Baylor is running on sustained success. Baylor is three years removed from being the worst overall football/basketball school of any major conference member. No BCS football conference school has a worse conference record since 1996. Only seven D-1 basketball programs have fewer conference wins since 1996, and most of them are in conferences I doubt you even know exist. And the fact that you bring up sports such as tennis as if that has any bearing on anything is laughable. A&M just won the women's basketball national title, and absolutely nobody cares. Football and to a much lesser extent basketball are where this discussion begins and ends, and even then it's about alumni bases and TV sets moreso than success.
Worst case scenario, we pay no more than the $9 million Colorado and Nebraska paid (none of which was actually their money anyway, simply forfeited TV revenue). The more likely scenario is that we leave, OU, Okie State, Tech and Texas immediately bolt fot the PAC, Kansas leaves for the Big East soon, the Big XII dissolves and nobody pays anything as there is no longer a conference to collect. Also, as soon as the conference number drops below 8 the TV contract becomes null and void and nobody has any claim to lost TV revenue.
In other words, no matter what we won't be writing anyone a check. We may simply leave a chunk of our $20 million in TV revenue for this season to be split amongst the remaining conference members.
