Tough to say at UTA. There have been some bad and very bad teams to be Rebels/Mavericks, but have had some good players on those teams. Marquis Haynes from a few years ago was UTA's first All-American and been close to making it to the NBA. Has played in Europe and the D-League.
In the '80's, the Southland, with all the players mentioned (but not Billy Tubbs, coach of Lamar), was one of the better basketball conferences in the country. Our most successful year culminated in a 2008 NCAA tourney appearance. But as far as talent, it was the '81 NIT team,

On that team, both Albert Culton and Ralph McPherson could score and rebound. They were a one-two threat that challenged Lamar's supremacy at the top of the SLC. If that team played today, rather than in '81, they likely would be conference champions by long margins. That's why I'd have to put Culton at the top of the list.
Willie Brand, UTA's career scoring leader by almost 500 points, is high on the list too.
