Former Texas governor William P. Clements, Jr.
I always thought Clements was an interesting character. He was the first Republican governor elected since Reconstruction; as a matter of fact, his campaign was the first (and only) political campaign I recall any of my family members volunteering for.
On the other hand, I wasn’t aware until many years later that Clements was involved up to his ears in the SMU scandal. (A Payroll to Meet is the definitive book on the scandal and Clements’ involvement, but don’t pay $245 for it.) On the gripping hand, I’m not sure Clements and SMU did anything that UT and A&M were not also doing at the time; SMU was just unlucky to get caught, and unlucky enough to be the test case for the “death penalty”. (Notice how the NCAA hasn’t used the “death penalty” since then?)
