Dominique Wilkins had an unfulfilled NBA career. He never made the conference finals and was eclipsed by the Holy Trinity of Michael Jordan, Magic Johnson and Larry Bird.
But there's no question he was one of the best dunkers in history.
Wilkins burst onto the dunking scene with a shocking win at the stacked 1985 Slam Dunk Contest, defeating Jordan, Julius Erving, Larry Nance, Clyde Drexler and Darrell Griffith. As the Atlanta Hawks weren't very prominent in the 1980s (and without League Pass, he couldn't be seen by most people outside of Georgia), Wilkins' dunk contest victories (won again in 1990) solidified his status as one of the premier aerial athletes alive, and he began approaching Holy Trinity status as a must-see player when his team came to town.
Of course, the dunks themselves were always spectacular too. Nique never cared who was in his way—just that if you stood between him and the basket, you'd be hurting in the morning (physically or psychologically).
