As a senior in 2013, Sam recorded 11.5 quarterback sacks and 19 tackles for a loss. He led the SEC in both categories, and tied Missouri's single-season record for sacks. He was named the SEC Defensive Player of the Week in two consecutive weeks, after recording three sacks apiece in games against the Arkansas State Red Wolves and the Vanderbilt Commodores. After the season, Sam was named the SEC Co-Defensive Player of the Year, with C. J. Mosley of the University of Alabama, and a first-team all-SEC selection.
Sam was named a first-team All-American by the Walter Camp Football Foundation, Associated Press, Sporting News, the American Football Coaches Association, and the Football Writers Association of America. He was also named a semifinalist for the Chuck Bednarik Award, the Hendricks Award, and the Lombardi Award. Missouri played in the 2014 Cotton Bowl Classic, in which Sam forced a fumble that was returned for a touchdown, securing Missouri's victory over the Oklahoma State Cowboys.
During his college career, Sam accumulated 123 tackles, including 36 for loss, 21 sacks, six forced fumbles and two intercepted passes. He graduated from Missouri in December 2013. He participated in the 2014 Senior Bowl in January 2014; considered too small to play as a defensive end in the National Football League (NFL), he played as an outside linebacker. Sam struggled at the new position.
He was seen as too small to play defensive end and too slow to play outside linebacker.
Sam made his professional debut on August 8, 2014 during the first preseason game against the New Orleans Saints, where he made one tackle in the game on quarterback Ryan Griffin. During the second preseason game against the New Orleans Saints, Sam recorded his first professional sack where he sacked Matt Flynn. In preseason game 3 against the Cleveland Browns, Sam sacked the fellow top-quality rookie Johnny Manziel.
In four exhibition games, Sam recorded 11 tackles and 3 sacks, including a team-leading 6 tackles in the final game. “I believe he can play in this league,” Rams coach Jeff Fisher said. On August 30, St. Louis released Sam as part of a final round of cuts to reduce their roster to the league-mandated 53 players before the start of the regular season. The Rams, who kept nine defensive lineman, chose to retain undrafted rookie Ethan Westbrooks over Sam. While their statistics were similar, Westbrooks provided the versatility to play all four defensive line positions, while Sam had been playing virtually exclusively as a left defensive end.
