Sean McVay
Sean McVay (born January 24, 1986) is an American football coach who is the head coach of the Los Angeles Rams of the National Football League (NFL). Upon his hiring in 2017 at the age of 30, he became the youngest head coach in modern NFL history. He was the offensive coordinator of the Washington Redskins from 2014 to 2016. He was named the AP NFL Coach of the Year in his first year of coaching, becoming the youngest person ever to win the award. After the Los Angeles Rams' appearance in Super Bowl LIII, McVay will become the youngest head coach ever to coach in a Super Bowl game.
George Allen (American football coach)
Allen and the 1969 Rams seemed to justify the coach's renewed presence; their 11–3 record earned them a Coastal Division title as Gabriel won the NFL's Most Valuable Player award. But in both 1969 and 1970 Allen's team could not produce the championship that many had predicted for them. At the end of 1970, with the Rams missing the playoffs and Allen's contract expiring, Reeves dismissed the coach again. It had been tacitly assumed that Allen had been granted the two extra years to bring the Rams a title, and so the second time the firing met with neither fan outrage nor player objection. Allen quietly left Los Angeles as the most successful coach in Rams history. He was replaced by UCLA coach Tommy Prothro, almost Allen's opposite in personality and approach.
