Lew Massey, the Charlotte 49ers’ second-leading career scorer and a key member of their 1977 Final Four team, died Thursday, a school spokesman confirmed Friday. Massey, a sweet-shooting 6-foot-4 forward who came to the 49ers from South Mecklenburg High, was 57. Massey is one of just four players in 49ers history to score 2,000-plus points in his career. His 2,149 points included 916 made field goals, a school record. He was also an iron man on the court, averaging 35.2 minutes per game over his career, fourth highest in school history. Massey, who was diabetic, was a two-time honorable mention All-American. He averaged 19.6 points and 6.7 rebounds during the 1976-77 season, when Charlotte advanced to the Final Four
