College statistics
Professional career
Coming out of college, Collins was projected by some analysts to be a second or third round selection.
Collins was selected by the Dallas Cowboys in the third round of the 2016 NFL draft. On July 13, 2016, the Cowboys signed Collins to a four-year, $3.22 million contract with $887,545 guaranteed and a signing bonus of $881,152. He was the last remaining Cowboys player of the 2016 draft class to be signed. He suffered a broken right foot during the first week of organized team activities, he was placed on the physically unable to perform list and missed most of the preseason. Collins began his rookie season as the fourth defensive tackle on the depth chart behind the veterans Tyrone Crawford, Terrell McClain and Cedric Thornton. Although he made his professional regular season debut in the Cowboy's season opening loss to the New York Giants, he did not record a statistic. The improved play he showed in the second game of the season against the Washington Redskins, made the Cowboys decide in the fourth quarter to move Crawford to left defensive end and keep Collins as the full-time one-technique tackle, where he was playing out of position. He finished the game with three combined tackles and multiple quarterback hurries. The following week, Collins earned his first career start at defensive tackle and made two combined tackles in the Cowboys' 31-17 defeat over the Chicago Bears. On November 9, 2016, Collins made his first career sack on Cleveland Browns quarterback Cody Kessler. He finished the 35-10 victory with three solo tackles and two sacks. He started at the three-technique tackle position against the Bears, 49ers, Bengals and Packers. During a Week 13 win over the Minnesota Vikings, Collins made two combined tackle and sacked Sam Bradford for his third of the season. On December 18, 2016, Collins made one solo tackle, and sacked Tampa Bay Buccaneers quarterback Jameis Winston causing a forced fumble, the first of his career, helping the Dallas Cowboys win 26–20. He finished second on the team with 5 sacks. On September 17, 2017, in Week 2 against the Denver Broncos, Collins's teammate DeMarcus Lawrence forced a fumble off of quarterback Trevor Siemian. The fumble was recovered by Collins and helped set up the Cowboys on a touchdown-scoring drive in the 42–17 loss. On May 14, 2018, Collins underwent foot surgery to repair the fifth metatarsal fracture, and was ruled out until at least August.
