15. Bernard King
Bernard King was absolutely amazing during his time period. The 1970s and 1980s were absolutely incredible for King as he literally could score on any defender. From his rookie year in 1977-1978 to the 1990-1991 season, he was able to score at least 21 points per game. Of course, this is barring the three seasons he was injured.
He was so impressive as a scorer that he managed to become the NBA Scoring Champion in the 1984-1985 season, with 32.9 points per game. King also managed to become a 4-time NBA All-Star during this point. It seemed like King was unstoppable even in the playoffs but he sadly still never won a ring. That lands him here on the best players who never won an NBA Championship list.
