Pat Smith did not win/wrestle in the 93 tournament. That was the year Ok State was banned. Since Smith wrestled/won as a Freshman, he was able to redshirt in 93. Others who did not have a redshirt to burn that year either transferred (e.g., Jaworsky) or lost a year (e.g., Fried).
The supposed wrongdoings I have heard about that led to the ban seem relatively innocuous. I don't recall previously hearing about money earned at camps, instead it was wrestlers in redshirt or otherwise not on the roster traveling to opens using team funds. Or something like that.
