Question: During the 1990 Los Angeles Rams season, which player from the University of Oklahama made his NFL debut?

<P0-S0> The 1990 Los Angeles Rams season was the team's 53rd year with the National Football League and the 45th season in Los Angeles. <P0-S1>  On November 11, 1990, Marcus Dupree made his NFL debut against the New York Giants. <P0-S2>  The Rams looked to improve on their 11-5 season from 1989 and make the playoffs for the 3rd straight season and be possible contenders for the Super Bowl. <P0-S3>  However, the Rams would struggle all season, starting 1-4 before winning 2 of their next 3 games before losing their next 2 games as they dipped to a 3-7 record. <P0-S4>  After a win over Cleveland, the Rams upset the 49ers 28-17 in San Francisco to improve to 5-7. <P0-S5>  However, this would be perhaps the only good highlight of the season for the Rams, as after the win, they ended the season on a 4 game losing streak as the Rams finished with a disappointing 5-11 record and missed the playoffs for the first time since 1987. <SEP> <P1-S0> The Los Angeles Rams, a professional American football team based in Los Angeles, joined the National Football League (NFL) as Cleveland Rams in 1937. <P1-S1>  The Rams began playing in 1936 as a charter member of the second American Football League. <P1-S2>  Although the NFL granted membership to the same owner, the NFL considers it a separate entity. <P1-S3>  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. <P1-S4>  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. <P1-S5>  The Rams moved to St. Louis in 1995 and renamed the team St. Louis Rams. <P1-S6>  In January 2016, the Rams and the NFL announced that the team would return to Los Angeles. <P1-S7>  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. <SEP> <P2-S0> The 2016 Los Angeles Rams season is the franchise's 79th season in the National Football League and the fifth and final under head coach Jeff Fisher. <P2-S1>  It is the franchise's 50th season in the Greater Los Angeles Area and the first since 1994. <P2-S2>  The Rams made their first appearance on HBO's "Hard Knocks" and also appeared on the new E! series "Hollywood & Football". <P2-S3>  The team returned to Los Angeles after 21 seasons in St. Louis. <P2-S4>  The Rams decided from 2016-2019 to return to wearing white uniforms at home as a nod to Fearsome Foursome era. <P2-S5>  In Week 15 against their NFC West Rival the Seattle Seahawks, the Rams used white horns on their helmet just for the one game only, a move which would be repeated for the entire following season. <SEP> <P3-S0> Marcus L. Dupree (born May 22, 1964) is a former American football player. <P3-S1>  He was born and grew up in Philadelphia, Mississippi, where his playing in high school attracted national attention. <P3-S2>  A highly touted and sought-after college football recruit, he played at Oklahoma, where he was named Football News Freshman of the Year, second team All-American and Big Eight Conference Newcomer of the Year. <P3-S3>  He left in the middle of his sophomore season and briefly attended the University of Southern Mississippi. <P3-S4>  Marcus played spring football for the Golden Eagles and finished college at the university.
