Background: Patrick James Riley (born March 20, 1945) is an American professional basketball executive, and a former coach and player in the National Basketball Association (NBA). He has been the team president of the Miami Heat since 1995 and head coach in two separate tenures (1995 through 2003, and 2005 through 2008). Regarded as one of the greatest NBA coaches of all time, Riley has served as the head coach of five championship teams. He won four with the Los Angeles Lakers during their Showtime era in the 1980s, and one with the Heat in 2006.
Context: After stepping down, Riley accepted a job as a television commentator for NBC. However, this job only lasted one year, and he became head coach of the New York Knicks starting with the 1991-92 season.  Commentators admired Riley's ability to work with the physical, deliberate Knicks, adapting from his style with the fast-paced Laker teams in the 1980s. The Chicago Bulls had easily swept the Knicks in 1991 en route to their first championship. However, in 1992 with Riley, the Knicks pushed the defending championship Bulls to seven games in the Eastern Conference semifinals. The physical defense of the Knicks against the Chicago Bulls' finesse superstars Michael Jordan and Scottie Pippen during the 1992 playoffs led to a feud between Riley and Bulls head coach Phil Jackson regarding the officiating and the Knicks' rough style of play. In 1993, Riley led the Knicks to their best regular season record in team history (tied with the 1969-1970 team) and received his second Coach of the Year award. The Knicks met the Bulls in the playoffs at the Eastern Conference finals where they lost in six games. Ironically, Jackson's Bulls went on to win the finals and accomplish the first "three-peat" in 1993, despite Riley's trademark in 1989.  Riley returned to the NBA Finals in 1994, en route defeating the three-time defending champions Bulls (without Michael Jordan) in seven games during the Eastern Conference semi-finals. However his Knicks lost in seven games to the Houston Rockets after being up 3-2 in the series. During the 1994 Finals, Riley became the first coach to participate NBA Finals Game 7 with two different teams, having been with the Lakers in 1984 and 1988. However, he had the unfortunate distinction of having become the first (and to date, the only) coach to lose an NBA Finals Game 7 with two different teams, having lost to the Celtics in 1984. It also denied him the distinction of becoming the first coach to win a Game 7 NBA Finals on two different teams, having defeated the Pistons in 1988.
