There are several errors in the article. But the biggest issue is the pro Texas slant. Deloss Dodds gets to give the pro Longhorn view, without the obvious issues that ESPN, source of the article, and UT destroyed the SWC and destroyed the Big 12. It was less their fault in the Southwest Conference. SMU, Baylor, TCU and Rice weren't pulling their weight. They had no TV attraction, and paid attendance at home games not including a state school barely reaching 20,000.s.
Houston joined the SWC party late. They weren't invited until the mid 70s. Then they won three conference championships in their first four seasons in the conference. However, they didn't draw much. Houston had a whole lot more A&M and Texas fans than it ever had UH fans. Yeoman's veer was hard to stop for a while. Eventually, all their presence did, was dilute Texas' and A&M's recruiting. Yeoman had been recruiting black athletes for a long time, before the Longhorns or Aggies had much more than token offers.
Heck, Duffy Daugherty had great teams at Michigan State in the mid-60s because he recruited Texas hard, especially the Gulf coast part of the state. He was born in Orange and grew up in Beaumont. But when he graduated from high school, nobody in the SWC recruited any black athletes. Warren McVea went to
the University of Houston, before anybody in the SWC offered a single African American.
The SWC might have survived. There were more great African American players from Texas, playing at colleges in every other state. I still believe that the start of the demise of the Southwest Conference did not come from the death penalty, or even Arkansas leaving. It was when SMU had the greatest recruit in the country 12 miles from their campus. Their coach wanted him. He chose SMU. Then the administration at SMU wouldn't take him, even though he qualified. It was a black eye for the whole conference. Four years later, Arkansas left.
Economics was the biggest factor, but the demise started with Larry Johnson going juco, then leading UNLV to the national title game twice, splitting with Duke.
