A 6'7" forward from the University of Portland, Powell was selected by the St. Louis Hawks in the eighth round of the 1965 NBA draft. He did not make the Hawks' roster, but he would soon blossom while playing for the American Basketball Association's Dallas Chaparrals. Powell averaged 18.3 points and nine rebounds in his first season with the Chaparrals, and two years later he represented Dallas in the ABA All-Star Game. Powell also spent time with the Kentucky Colonels, Utah Stars, and Virginia Squires, and he ended his ABA career in 1975 with 9,746 total points. Powell is a first cousin of former United States Secretary of State Colin Powell. Powell's son, Cincy Jr. died in 2004 at age 35, the result of Juvenile Diabetes. Powell is an inductee in the University of Portland Hall of Fame.

The American Basketball Association (ABA) was a men's professional basketball league from 1967 to 1976. The ABA merged into the National Basketball Association (NBA) in 1976, resulting in four ABA teams joining the NBA and the introduction of the NBA 3-point shot in 1979.
