6. Patrick Ewing
Patrick Ewing is one of the greatest Centers in NBA history. His numbers prove this but the dominance he had during his career more than shows that he should have at least won one ring. Sadly, he never did. However, Ewing is an 11-time All-Star for a legitimate reason. Numbers-wise, he was able to run roughshod through the league from his rookie year, on.
From 1985 to 1998, the man averaged 20 points per game with an average of 24 from 1989 to 1995. Ewing was also a skilled rebounder and defender. From 1989 to 1999, he averaged 10 rebounds per game and from 1985 to 1999, he averaged 2.4 blocks per game. He had a few seasons of 3 or 4 blocks per game as well. However, he never made the defensive first team.
Despite this, Ewing did play in the NBA Finals before his career was up. Sadly, his team, the New York Knicks, did not win.
