Question: What is the birthday of the coach who designed the NFL offense "The Greatest Show on Turf" for the St. Louis Rams?
Context: The Los Angeles Rams, a professional American football team based in Los Angeles, joined the National Football League (NFL) as Cleveland Rams in 1937.  The Rams began playing in 1936 as a charter member of the second American Football League.  Although the NFL granted membership to the same owner, the NFL considers it a separate entity.  In 1946, Rams' owner Dan Reeves, fed up with poor attendance at Cleveland Stadium, moved the Rams to Los Angeles, and the team played there from 1946 to 1979.  Before his death in 1979, later Rams owner Carroll Rosenbloom planned a move within the Los Angeles metropolitan area to Anaheim, using the venue now known as Angel Stadium, and his widow and successor Georgia Frontiere went through with the move in 1980, with the team still officially representing Los Angeles.  The Rams moved to St. Louis in 1995 and renamed the team St. Louis Rams.  In January 2016, the Rams and the NFL announced that the team would return to Los Angeles.  The team now plays in its original L.A. venue, the Los Angeles Memorial Coliseum, while awaiting the 2020 opening of its new stadium in suburban Inglewood. The 2003 St. Louis Rams season was the team's 66th year with the National Football League and the ninth season in St. Louis.  The Rams were coming off a disappointing 7–9 season and former MVP Kurt Warner was demoted to backup quarterback; Marc Bulger earned the starting job after replacing Warner in 2002 and winning six of his seven starts.  Though many agree that The Greatest Show on Turf ended after the 2001 season, the Rams nonetheless finished 12–4, winning the NFC West, only to lose to the eventual NFC champions Carolina Panthers. The professional American football franchise now known as the Los Angeles Rams played in St. Louis, Missouri, as the St. Louis Rams from the 1995 through the 2015 seasons.  The Rams franchise relocated from Los Angeles to St. Louis in 1995, which had been without a National Football League (NFL) team since the Cardinals moved to Phoenix, Arizona, in 1988.  The Rams' first home game in St. Louis was at Busch Memorial Stadium against the New Orleans Saints on September 10, 1995, before the Trans World Dome (later the Edward Jones Dome, and now known as The Dome at America's Center) was completed for their November 12 game against the Carolina Panthers.  Their last game played at the Edward Jones Dome in St. Louis was against the Tampa Bay Buccaneers on December 17, 2015, which they won, 31–23.  The Rams' last game as a St. Louis-based club was on January 3, 2016, against the San Francisco 49ers at Levi's Stadium, where they lost in overtime 19–16. The 2000 St. Louis Rams season was the team's 63rd year with the National Football League and the sixth season in St. Louis.  The Rams finished the regular-season with a record of 10–6 but would go on to lose to the New Orleans Saints in the Wild Card round of the playoffs.  They led the NFL in scoring for a second straight year with 540 points.  The Rams became the first team in NFL history to score more than 500 points on offense, while allowing more than 450 points on defense. Orlando Lamar Pace (born November 4, 1975) is a former professional American football player who was an offensive tackle in the National Football League (NFL) for thirteen seasons.  He played college football for Ohio State University, and was twice recognized as a unanimous All-American.  He was drafted by the St. Louis Rams, first overall in the 1997 NFL Draft, and played professionally for the Rams for twelve years.  Pace started all 16 regular season games eight times in his pro career, and blocked for three straight AP NFL MVPs (Kurt Warner in 1999, 2001; and Marshall Faulk in 2000).  He was the cornerstone of a Rams offensive line that blocked for an offense that compiled more gross yards than any other team during his 12 years in St. Louis (50,770 in 12 seasons), finished second in completion percentage (61.8 percent) and fifth in touchdown passes (289) over that time.  Under Pace's protection, the Rams' passing offense compiled more than 3,000 yards in all 12 of his NFL seasons, seven different quarterbacks eclipsed the 3,000-yard mark in a season, including three times surpassing the 4,000-yard mark, and blocked for seven 1,000-yard rushers.  Pace started 154 consecutive games, playing with the St. Louis Rams and Chicago Bears (2009). Michael Martz (born May 13, 1951) is a former National Football League (NFL) head coach and offensive coordinator.  He is best known as the offensive coordinator behind the St. Louis Rams high-powered 1999 team which won the Super Bowl.  As a head coach in the NFL, Martz's St. Louis Rams teams compiled a 56–36 record in his 5⅓ seasons as head coach.  His teams reached the playoffs four times and won two division titles including a NFC championship and a trip to Super Bowl XXXVI. Thomas E. "Ted" Plumb (born August 20, 1939) is a former American football player & coach.  His playing career ended after a neck injury in training camp as he looked like a promising young receiver for the Buffalo Bills out of Baylor University.  Although his playing career was cut short by injury, it helped lift him into what became a long and exciting coaching career in: High School, College, & onto the NFL.  Ted Plumb's NFL coaching career is special and unique as he was a coach for two of the most legendary Super Bowl champions in the history of the NFL; The Super Bowl XX Champion 1985 Bears, and the Super Bowl XXXIV Champion 2000 St. Louis Rams.  Teddy served as the Wide Receivers Coach with the "Monsters of the Midway" Chicago Bears, and he served as the Director of Pro Scouting for the "Greatest Show on Turf" 2000 St. Louis Rams (according to the St. Louis Post-Dispatch April 19, 2000).  Plumb retired after that 2000 season to his home in Alba, Texas. "The Greatest Show on Turf" was a nickname for the record-breaking offense of the St. Louis Rams during the 1999, 2000, and 2001 National Football League seasons.  The offense was designed by attack oriented offensive coordinator Mike Martz who advocated mixing both an aerial attack and aued yardage, three NFL MVP honors, and two Super Bowl appearances for the 1999 and 2001 seasons, of which they won the former. The 2010 St. Louis Rams season was their 73rd season for the franchise, and their 16th overall in St. Louis.  St. Louis greatly improved on their near winless record of 1–15 from the 2009 season by achieving more total victories, with a record of 7–9, than in their previous 3 years.  Since the start of the 2007 NFL season, the Rams had won just 6 combined games, and have not qualified for the playoffs since 2004.  In the 2010 NFL Draft, the Rams had the number 1 overall pick, which they picked Sam Bradford from Oklahoma.  This year marked their second season under head coach Steve Spagnuolo.  The Rams played all of their home games at the Edward Jones Dome, in St. Louis, Missouri. Torry Jabar Holt (born June 5, 1976) is a former professional American football player who was a wide receiver in the National Football League (NFL) for eleven seasons.  He was named to the Pro Bowl seven times and retired with the 10th most receiving yards, including a record six consecutive seasons with 1,300 yards.  He played college football at North Carolina State University, and earned consensus All-American honors.  He was drafted by the St. Louis Rams in the first round of the 1999 NFL Draft, and spent the next ten years with the Rams and is remembered as one of the members of the "Greatest Show on Turf."
