With the NBA All-Star Weekend just around the corner, we look at an interesting rule related to the selection of All-Star coaches every year.Pat Riley has won three NBA Coach of the Year awards along with five NBA championships. He was a driving force behind the LA Lakers’ success during the 1980s. Traditionally, the All-Star coaches are the two best coaches from either conference. Riley’s rule was created after Pat Riley was selected as the Western Conference coach eight times in 9 seasons from 1982 to 1990.

The rules pertain to the representation of coaches in consecutive All-Star Games.In the 1980s, the Los Angeles Lakers, led by Pat Riley, were a dominant force in the league, particularly in the Western Conference. This led to Riley being named the head coach of the Western Conference All-Star team in eight of the nine seasons from 1982 to 1990.The repeated selection to coach the All-Star team caused concern that it was taking away from the excitement and unpredictability of the event. To address this issue, the NBA introduced a rule that prevents a coach from representing their conference in two consecutive All-Star Games. The Riley rule ensured that other deserving coaches had the opportunity to lead their conference's All-Star team.Under the "Riley Rule," if a coach has already led their conference's All-Star team in one year, they cannot be selected to coach in the following year's game. Instead, the coach of the second-best team in the conference will take over the position. This rule has been in place since the 1990-91 NBA season, and it has allowed for more diverse and exciting coaching selections for the All-Star Game.NBA on TNT@NBAonTNT"I always say Pat Riley set the standard, but Coach Spo improved on it."@DwyaneWade on Erik Spoelstra being named as one of the 15 greatest coaches in NBA history.4033893"I always say Pat Riley set the standard, but Coach Spo improved on it."@DwyaneWade on Erik Spoelstra being named as one of the 15 greatest coaches in NBA history. https://t.co/ltT5yyfnn8Pat Riley was not only a dominant coach for the LA Lakers but also brought about a rule change.
