The dunk from the freethrow line was first done by Julius Erving, better known as Dr. J. Â However this dunk was popularized by Michael Jordan who used it to help him win the 1988 Slam Dunk contest. Â It’s also where he earned the name “Air Jordan”. Â The dunk has been attempted and done by many since then but none like Michael. Â Check the video out after the jump.
