He attended Michigan State University, before transferring to the University of Southern California after his sophomore year, where he became a standout defensive tackle and a member of the original "Wild Bunch". Smith teamed in the defensive line with Al Cowlings, Jimmy Gunn, Willard "Bubba" Scott, and Charlie Weaver to form in 1969 "The Wild Bunch," which was key for USC to compile a 10-0-1 record and a No. 3 ranking after a victory over the Michigan Wolverines in the 1970 Rose Bowl. The Wild Bunch was a hit movie in 1969 and it was Cowlings who dubbed the defensive line 'The Wild Bunch' for their reckless abandon and hard-nosed style of play. Playing in an era of powerful running games, they allowed just 2.3 yards per carry and a league-low 95.6 rushing yardsa game. Smith was one of the five USC African American starters, that played against an all-white University of Alabama football team, winning 42–21 in Birmingham on September 12, 1970. This game was historically significant, because it was a factor in convincing the University of Alabama and its fan base to accelerate the integration of its football team. He played two seasons for the Trojans. In 1969, he was honorable-mention All-PAC-8 and in 1970 he was a second-team All-American, even though he played only four games as a senior, after spraining an ankle in the second game. There is a statue of him and the other four "Wild Bunch" defensive linemen at USC's Heritage Hall. He also appeared in the famed gunslinger photo of the five of them.
Smith was selected by the Dallas Cowboys in the 1st round of the 1971 NFL Draft, after dropping because of an ankle injury he suffered in college. This injury limited him to only 7 games during his rookie year. He spent the first seven games of the season on the team's taxi squad, but when he joined the regular roster, he showed the Cowboys he had a future in the NFL and even contributed in the Cowboys win in Super Bowl VI. Although he had surgery during the off-season on an injured knee, head coach Tom Landry seemed convinced Smith had the capability to start in 1972. He had a disappointing second year where he only played 10 games. On May 9, 1973, he was traded along with wide receiverBilly Parks to the Houston Oilers, in exchange for their first and third round draft picks in the 1974 NFL Draft. For the first time in their history, the Dallas Cowboys would have the first overall draft choice which they used to select defensive end Ed "Too Tall" Jones, who would play a key role on the Cowboys Super Bowl teams in the 1970s. With the third round pick they acquired, the Cowboys selected quarterbackDanny White, who became the starting quarterback during the 1980s after the retirement of Roger Staubach.

Smith was a starter for the Houston Oilers for the next 3 seasons, before being waived injured with an ankle sprain in 1976.
Buffalo Bills
On November 23, 1976, he was claimed off waivers by the Buffalo Bills. He played in only 2 games and retired at the end of the season.
On July 11, 1977, he was signed as a free agent by the Tampa Bay Buccaneers, but was released before the season started on September 1st.
