Clinton Earl Portis (born September 1, 1981) is a former American football running back who played in the National Football League (NFL) for nine seasons. He played college football for the University of Miami. He was drafted by the Denver Broncos in the second round of the 2002 NFL Draft. Portis was best known for being the starting running back for the Washington Redskins for seven seasons, in which he gained an average of 81.2 yards rushing per game, for which a select panel of celebrities included him as one of the 80 Greatest Redskins.
Portis enrolled in the University of Miami, where he played for the Miami Hurricanes football team. He considered going to the University of South Carolina but a fight that he had at Gainesville High School resulted in his scholarship being taken away. He became just the second true freshman to start at running back since the 1975 season. Portis set a school freshman record with five 100-yard performances, and led the team with 838 yards and eight touchdowns on 143 carries (5.9 avg.) in 10 games. He also caught four passes for 44 yards (11.0 avg.) and 2 touchdowns. When Portis was still a relative unknown, Lee Corso singled out Portis's performance during a defeat by Florida State for hustling and never giving up, saying "that kid can play for me any time".
