At his graduation, Rick held the University of Missouri career record for quarterback sacks. Lyle was in the top five all time at MU in the five weight lifts used to judge overall strength and was the top lifter in their history at that time in the Power Clean. He was also indoor champion in the shot put and eventually became an outdoor All-American in the shot put, and also held several University of Missouri records. Rick will be inducted into the University of Missouri Athletic Hall of Fame in January.

Lyle signed a free agent contract with the Cleveland Browns under Bill Belichick as head coach after graduation from Missouri. He stayed with them through two years, although he missed the second year after a training camp injury required surgery. He then moved with the team to Baltimore, where he played as a Raven for one year. The next five years were with the New York Jets, under Bill Parcells and Bill Belichick and later Herman Edwards. During his time there, he started 67 consecutive regular season and playoff games, including the 1998 Jets versus Broncos American Conference Championship Game. Lyle's last two seasons in the NFL were with the New England Patriots, once again with Belichick, as he was with the Browns and the Jets. His last game was Super Bowl XXXVIII, the Patriots' win over the Carolina Panthers.

After his retirement from the NFL, Lyle and his family moved to the St. Louis area where he worked as an assistant coach at Marquette High School, a local high school. In 2006, Eric Mangini asked Rick to join his new staff when he became head coach of the New York Jets. Lyle serves as an assistant strength and conditioning coach and is responsible as well to see that the team's food, both at their facilities and on the road, is prepared and served properly, and especially, safely.
