College career
Bakersfield College
Crawford was recruited by Boise State University and Michigan State University, but the academic curriculum from his Canadian high school didn't meet NCAA requirements, so he enrolled at Bakersfield College in 2008. After concentrating on just playing football and the defensive end position, he appeared in 9 games and was named first-team All-conference as freshman in 2008, while collecting 38 tackles (13 for loss), 6 sacks, one pass breakup and one fumble recovery.
As a sophomore in 2009, he was honored as a junior college first-team All-American and was named to both first-team all-state and conference. He also was awarded as the defense's most valuable player for the Renegades. He registered 42 tackles (led the team), including 8 sacks and 14 tackles for loss.
Considered a four-star recruit by Rivals.com, Crawford was ranked as one of the most talented JUCO prospects in the nation.[2] He committed to Boise State University.
Boise State University
In his first season at Boise State University, as a junior in 2010, Crawford appeared in each of the Broncos 13 games as a back-up weak-side defensive end. He registered 32 tackles on the season (13 solo), 13.5 tackles-for-loss (tied for the team lead), 7 sacks (second on the team), one forced fumble, one fumble recovery, one pass breakup and one blocked kick.
As a senior in 2011, Crawford started in 11 games, recording 44 tackles (20 solo), 6.5 sacks (led the team) and 13.5 tackles for loss (led the team). He was named first team All-Mountain West Conference for his performance.
Entering 2014, there were initial plans to evaluate Crawford in the 3-technique defensive tackle spot vacated by free agentJason Hatcher, but after the signing of Henry Melton he was kept at defensive end. During the regular season Melton struggled as he recovered from offseason surgery and worked through a groin strain, so Crawford was forced to play defensive tackle in week 3 against the New Orleans Saints and would earn the starter job. He finished with three sacks and 29 quarterback pressures.
In 2015, Crawford was signed to a five-year, $45 million contract ($25.7 million guaranteed). He was limited with a torn rotator cuff in his right shoulder that required offseason surgery, suffered in the second game of the season against the Philadelphia Eagles.[8] He still managed 44 tackles, 5 sacks (third on the team), and 27 quarterback pressures (third on the team).
In 2016, Crawford struggled at the beginning of the season playing defensive tackle. The production of Terrell McClain and rookie Maliek Collins, combined with the need the team had at defensive end, made the Cowboys decide to move him to left defensive end in the fourth quarter of the second game of the season against the Washington Redskins. He would remain the starter at left defensive end for the rest of the season. His best game came in week 8 against the Philadelphia Eagles, registering 5 quarterback hurries, 1.5 sacks, 2 tackles for loss and a fumble recovery. He posted 2 sacks against the Cleveland Browns. He had to be replaced against the Tampa Bay Buccaneers with David Irving, because he was playing through shoulder and hamstring injuries. He started 14 games did not play in the last 2 contests of the season, because he was being saved for the playoffs. He finished with 21 tackles (6 tackles for loss), 4.5 sacks (third on the team) and 17 quarterback pressures (second on the team).
In 2017, he suffered an ankle injury in training camp on August 8, that looked at the time to be a season ending injury.[9] He missed most of the preseason. He was a backup during the first 2 games of the season, until being moved to right defensive end to help improve the rushing defense.[10] In Week 8 against the Washington Redskins, he had 3 tackles, one quarterback pressure, one forced fumble and blocked a 36-yard field goal attempt, in which teammate Orlando Scandrick returned 90 yards in the 33-19, earning him NFC Special Teams Player of the Week.[11] He started 14 out of 16 games, collecting 38 tackles (2 for loss), 4 sacks (third on the team), 26 quarterback hurries (second on the team), 2 pass breakups, one forced fumble, one recovery and one blocked field goal attempt.
In 2018, Crawford was switched back to defensive tackle after Maliek Collins and David Irving both started the league season with injuries or suspensions. He also started games at right defensive end and made his 200th career tackle in the eleventh game against the Washington Redskins. He was bothered by bursitis in his hips late in the season.[12] He was declared inactive in the season finale with a neck injury. He started 15 games, posting 33 tackles, 5.5 sacks (third on the team) and 25 quarterback hurries.
In 2019, he missed the entire offseason conditioning program and training camp while recovering from his hip injury. He started the first 2 games of the season, before being held out in the next 2 outings. He returned to play as a backup in Week 5 and Week 6. On October 15, he was placed on injured reserve after undergoing season-ending hip surgery.[13] He finished with 2 tackles (one for loss), one sack and one quarterback pressure.
On July 28, 2020, he was placed on the active/physically unable to perform list at the start of training camp, still recovering from his double hip surgery.[14] He was activated on August 14.[15] He was placed on the reserve/COVID-19 list by the team on November 11,[16] and activated on November 18.[17] He struggled with his physical health during the season, appearing in 16 games with 3 starts. He had 17 tackles (2 for loss), 2 sacks and 14 quarterback hurries.
Cowboys head coach Mike McCarthy announced Crawford's intention to retire from professional football on March 25, 2021.[18]
