Crockett played three seasons with the Colts, (1995–1997). During his rookie year he only recorded 1 rushing attempt during 16 games during the regular season. Perhaps one of his finer pro career moments came during the 1995 AFC Wildcard game, where he started in place of an injured Marshall Faulk. During this game against the San Diego Chargers, Crockett rushed for 147 yards and scored 2 touchdowns to help the Colts win their first playoff game in 24 years. During his final two seasons with the Colts, Crockett started 16 of 21 games played, accumulating a total of just 464 yards on 126 carries (3.64 YPC) and one touchdown.
After being released by the Colts, Crockett played for the Jacksonville Jaguars in 1998 playing in 12 games, and starting two of them. The next year, he was a free agent and found his home, with the Oakland Raiders. In 2001, he led the Raiders in regular season rushing touchdowns, with six. In 2002, he surpassed Jon Ritchie and became Oakland's full time starter. That postseason, Crockett, by then regarded as a “short-yardage specialist”,[3] scored a touchdown during a 30–10 win over the New York Jets in the divisional round. In 2003, he led the Raiders with eight rushing touchdowns.
On September 1, 2007, the Raiders released him. On October 10, 2007, signed with the Tampa Bay Buccaneers and on October 23, 2007, they released him. He was re-signed on December 12 and was released again on December 19. He was claimed off waivers by the Dallas Cowboys on the same day. After practicing some with the Cowboys and being inactive for his first game with them, he was cut on December 24, 2007.
Adept at cooking, Crockett is a Gourmet chef and his favorite dish to prepare for family is Peking Duck and Lamb Chops. His favorite film is Pulp Fiction. He also enjoys traveling the world to different luxurious resorts and learning different cultures. Being an avid traveler and finally relaxing is something he is looking to do in the future, and he is a member of Omega Psi Phi fraternity.
