Larrimore attended Locke High School, where he played only one year of football as a cornerback and returner. Because of poor grades, he spent one year after graduating earning his GED, before walking-on at Cerritos Junior College where he was named junior college All-American in his second year. After the gang-related death of his brother, he transferred to West Texas A&M, where he received Division II All-American and All-Lone Star Conference honors. As a junior in 1998, he had 34 tackles, two interceptions and 7 passes defensed, along with 20 kickoff returns for 532 yards and one touchdown of 100 yards. As a senior in 1999, he missed the season opener, but played the rest of the year and had 32 tackles, 5 interceptions and 10 passes defensed, along with 15 kickoff returns for 318 yards. After the season, he played in the Blue-Gray All-Star Game, where he returned a kickoff 99 yards for a touchdown, which was a first in the 62-year history of the game. He also played in the Senior Bowl.
Professional career
Dallas Cowboys
Larrimore was selected by the Dallas Cowboys in the fourth round of the 2000NFL Draft, after dropping because of character concerns and failing a marijuana test in the scouting combine. He impressed the team with his athletic ability from the beginning and moved ahead of fellow rookie draft picks Dwayne Goodrich and Mario Edwards. Two weeks into training camp, he was named the starter at left cornerback in place of a retired Kevin Smith. He was just the second rookie in franchise history to start at cornerback in the season opener, but he struggled and was replaced with the more experienced Phillippi Sparks after the fourth game of the season. The move didn't sit well with him and violations of team rules started to affect his standing with the team. In 2001, he was suspended for the final preseason game, the season opener and fined for missing curfew when the Cowboys traveled to Mexico City to play the Oakland Raiders in the American Bowl. He eventually was released on October 23, with reports later surfacing that he had been fined at least 11 other times for various reasons. Larrimore played for the Cowboys for two seasons, appearing in 19 regular season games and starting in 6 games.
Dallas Desperados (AFL)
On May 21, 2002, he signed with the Dallas Desperados of the Arena Football League, who were owned by Jerry Jones, who also owned the Dallas Cowboys. As a rookie, he played in nine games, earning the position as the team’s top kick returner and defensive specialist. He received AFL All-Rookie honors after finishing with 24.5 tackles, 5 passes defensed and one interception. In 2003, knee and back injuries limited him to seven games, while spending time on the Reserve/Injured list three times. He recorded 26.5 tackles, 4 passes defensed, 2 interceptions and 27 kickoff returns for 476 yards.
Chicago Rush (AFL)
Larrimore was selected by the Austin Wranglers in the league's expansion draft, but was traded to the Chicago Rush in exchange for Cedric Walker on October 15, 2003. He was waived on April 7, 2004, after registering 11 tackles, one interception, 21 kickoff returns for 485 yards and 2 touchdowns.
