Question: Who was selected fourth overall by the Toronto Raptors in a draft class that included multiple future NBA superstars such as LeBron James, Dwyane Wade and Carmelo Anthony, and had a season begin  after a much anticipated off-season as the All-Star  became a free agent in the 16th season of the Toronto Raptors?

 A high school "Mr. Basketball" in Texas, Bosh left Georgia Tech after one season to enter the 2003 NBA draft. Christopher Wesson Bosh (born March 24, 1984) is an American professional basketball player who is currently a free agent.  He was selected fourth overall by the Toronto Raptors in a draft class that included multiple future NBA superstars such as LeBron James, Dwyane Wade and Carmelo Anthony.  While at Toronto, Bosh emerged as one of the young stars in the league; he became a five-time NBA All-Star, was named to the All-NBA Second Team once, appeared for the U.S. national team (with whom he won a gold medal at the 2008 Summer Olympics), and supplanted former fan-favorite Vince Carter as the face and leader of the Raptors franchise. <SEP> The 2010–11 Toronto Raptors season is the 16th season of the Toronto Raptors in the National Basketball Association (NBA).  Bosh would eventually sign with the Miami Heat teaming up with fellow NBA Superstars LeBron James and Dwyane Wade causing the Raptors to start rebuilding.  They finished with a 22-60 record missing the playoffs for a third-straight year.  The season began after a much anticipated off-season as All-Star Chris Bosh became a free agent. <SEP> The 2003–04 NBA season was the 28th season for the Denver Nuggets in the National Basketball Association, and their 37th season as a franchise.  The season saw the team draft future All-Star Carmelo Anthony with the third overall pick in the 2003 NBA draft.  During the offseason, the team signed free agent Andre Miller, and re-signed former Nuggets guard Voshon Lenard.  Coming off with the worst record of 17–65 the previous season, Anthony led the Nuggets to a fast start winning 13 of their first 19 games.  However, the team struggled down the stretch posting losing records in February and March.  The Nuggets finished sixth in the Midwest Division with a 43–39 record, and made the playoffs for the first time since 1995.  Anthony had a stellar rookie season averaging 21.0 points per game, and being selected to the All-Rookie First Team.  He also finished second behind LeBron James of the Cleveland Cavaliers in Rookie of The Year voting. <SEP> The 2011–12 Miami Heat season is the franchise's 24th season in the National Basketball Association (NBA).  They came into the season as the defending Eastern Conference champions, the second season playing with the "Big Three" of Dwyane Wade, LeBron James, and Chris Bosh, and the fourth season under head coach Erik Spoelstra.  Prior to the beginning of the season, they looked to bounce back from their disappointing finish to the previous year where they lost to the Dallas Mavericks in the NBA Finals.  Following the 2011 NBA lockout the Heat played only 66 games this season.  They won their division for the 9th time and appeared in the Eastern Conference Finals for the 5th time.  For the second year in a row, Dwyane Wade, LeBron James, and Chris Bosh were all selected to the NBA All-Star Game, tying the record for the most Heat players in an All-Star game in franchise history.
