Hailing from Silver City, Mississippi, Spencer Haywood probably has the most unique entry story into the realm of professional basketball than anyone else on this list. After moving to Detroit in 1964, Haywood led his high school basketball team to the state championship game and won in 1967. Later, he found himself averaging an insane 28.2 points and 22.1 rebounds per game while attending a community college. He was contacted to join the Men's US National Basketball Team for the 1968 Summer Olympics where he would go on to lead the team in scoring averaging 16.1 points per game and setting a United States field goal percentage record of 71%.
Following the Olympics, Haywood transferred to the University of Detroit where he revealed that he would go pro following his sophomore year of college. The NBA denied Haywood's request to enter the NBA Draft due to the rules stating that he would enter with his graduating class. Haywood being the forward-thinking young man that he was, he joined the ABA and won Most Valuable Player before being drafted to the Seattle Sonics in 1970. Haywood would go on to become an NBA Champion with 1980 Los Angeles Lakers and 4x NBA All-Star. Way to work the system, Spencer.
