Dismantling of Big Xll Has Begun

About 14 years ago, the old Southwest Conference, which included Texas, Texas A&M, Baylor, Texas Tech, SMU and TCU was broken up. Just about every school in that league had been cheating by breaking NCAA rules left and right. SMU and TCU went there separate ways, eventually ending up in the WAC and Mountain West respectively.
The old Big Vlll Conference which included Kansas, Oklahoma, OK St., Iowa St., Nebraska, Missouri, Kansas St. and Colorado merged with Texas, Texas Tech, Texas A&M and Baylor to form the current Big Xll back in 1996. Now, the Big Xll is headed to join the Southwest Conference as ancient relics of college athletics. Nebraska has decided to join the Big 10, making it the Big 10 + 3. Colorado is joining the PAC 10, which is poised to add Texas, Texas Tech, Oklahoma, OK St. and Baylor making it the NCAA's first ever 16 team conference.
So what does Kansas, Kansas St., Iowa St. and Missouri do? Texas A&M is considering joining the SEC. The Mountain West Conference, who added Boise St to the fold over the weekend, is also courting the Jayhawks, Wildcats, Cyclones and, perhaps, the Missouri Tigers. This will certainly improve the MWC as a basketball conference. The addition of Kansas and K St. along with New Mexico, BYU and Utah. The MWC is a better football conference for Boise St. It gives them more legitimacy in the eyes of the BCS, as if they really needed more legitimacy. The new PAC 10 as a basketball conference would certainly be improved on with the arrival of the Longhorns, Bears, Cowboys and Sooners to go along with the traditions of UCLA and Arizona, and a solid Washington program.
But here is my question. Why won't the Big Xll fight for its survival? It has been a very successful conference. In football, its members, such as Nebraska, Oklahoma and Texas have played for the National Championship numerous times and have won the trophy at least twice in the decade. They've also had tremendous success as a basketball conference reaching the Final Four and winning a national title (Kansas) in 2008. If its about money and the large television markets, they have the Dallas / Fort Worth area, Houston, which is the fourth largest market in the country, St. Louis, Kansas City, San Antonio and Denver. I guess that's not enough.
I would like to see the Big Xll fight to survive. Why not try to grab TCU away from the MWC, or UTEP from the WAC, or Tulsa from Conference USA. They could at least be a decent basketball conference if not football. It seems as if this came on so sudden and out of nowhere. That's impossible, however. This has been talked about for a long time, probably at least 5 to 10 years. The Big Xll is doomed, but it was a tremendously successful conference. I hate to see it go.
