#4 Ron Simmons
Ron Simmons was the first African-American World champion in WCW, and had a memorable tenure in WWF/E as Farooq, winning the WWF Tag Team championships on 3 separate occasions with Bradshaw in the APA.
After a successful career in college football and as part of the Cleveland Brown's team, Simmons joined Jim Crockett Promotions (eventually WCW) and stayed for over 7 years. Leaving WCW due to falling down the card and shortly before finally signing with WWF, Simmons joined Paul Heyman in ECW in late 94 to bring in some top talent into the ECW main event scene. Progressing feuds with ECW champion Shane Douglas and Mikey Whipwreck over the course a few months, the run wasn't anything special and the offer from WWF soon came for Simmons. Damn!
