Military personnel in uniform are required to salute when they meet and recognize persons entitled (by grade) to a salute except when it is inappropriate or impractical (in public conveyances such as planes and buses, in public places such as inside theaters, or when driving a vehicle).
One notable player, Shawn Kemp, enrolled in college but never played any games due to personal problems. In 1989, a year after his high school graduation, he was drafted by the Seattle SuperSonics. He played 14 seasons in the NBA and was selected to 6 All-Star Games and 3 All-NBA Teams.
LeBron James (and technically James Jones, too) just did something nobody has done in 50 years. With the Cleveland Cavaliers' Eastern Conference Finals win over the Atlanta Hawks, LeBron James clinched a bid to the NBA Finals for the fifth straight year. It's been a long time since anybody has done that. Yes, only 10 players in NBA history have been to the NBA Finals in five straight seasons. Eight of them played on the Boston Celtics in the 1960s, and of those, seven are in the Naismith Basketball Hall of Fame as a player. The other two players are LeBron James and James Jones.
