In which season and year did Michael Jordan win Rookie of the Year?

In 1984 Jordan was drafted by the Chicago Bulls. In his first season (1984–85) as a professional, he led the league in scoring and was named Rookie of the Year; after missing most of the following season with a broken foot, he returned to lead the NBA in scoring for seven consecutive seasons, averaging about 33 points per game. He was only the second player (after Wilt Chamberlain) to score 3,000 points in a single season (1986–87). Jordan was named the NBA’s Most Valuable Player (MVP) five times (1988, 1991, 1992, 1996, 1998) and was also named Defensive Player of the Year in 1988. In October 1993, after leading the Bulls to their third consecutive championship, Jordan retired briefly and pursued a career in professional baseball. He returned to basketball in March 1995. In the 1995–96 season Jordan led the Bulls to a 72–10 regular season record, the best in the history of the NBA (broken in 2015–16 by the Golden State Warriors). From 1996 to 1998 the Jordan-led Bulls again won three championships in a row, and each time Jordan was named MVP of the NBA finals. After the 1997–98 season Jordan retired again.
