To ensure that a different coach represents their conference each year, there is a rule against a head coach making a consecutive appearance. Instead, the coach with the next best record is selected. This rule is known as the "Riley Rule" and was introduced in the early 1990s after the dominance of the 1980s Los Angeles Lakers team in the Western Conference, which was coached by Pat Riley. For the 2018 NBA All-Star Game, the format of the game changed to be played between two team captains, from the Western and Eastern Conference respectively, where the selection of the other players for each team are selected from any conference. However, the rules in which the head coach is selected still stands. Red Auerbach, the head coach for the Boston Celtics between 1950-1966, was selected to coach in the NBA All-Star Game a record 11 times.
