Possibly the greatest, or at least the most successful, athlete to ever emerge from Twinsburg is James Posey. He attended Twinsburg Chamberlin High School and was named the Division II high school basketball player of the year as a senior, in 1995. Aptly capable of playing all five positions, the versatile six-foot-eight senior averaged 24.5 points and 12 rebounds per game. After graduating from Chamberlin, he went on to star at Xavier University. He ranks sixteenth in scoring and tenth in rebounding in the history of Xavier Musketeers basketball. His collegiate success lead to the Denver Nuggets of the National Basketball Association selecting him with the eighteenth pick of the NBA draft. In the NBA, he excelled as a defensive stopper and clutch shooter for numerous teams over the course of his twelve-year career. Twice he was a crucial member of championship winning teams, first with the Miami Heat in 2006 and two years later with the Boston Celtics. Today, he is an assistant coach for the NBA champion Cleveland Cavaliers.
