Sean McVay
On January 12, 2017, McVay was hired to become the 28th head coach of the Los Angeles Rams at the age of 30 years, 11 months, 19 days. The Rams had made him the youngest head coach in modern NFL history, surpassing Lane Kiffin, who was 31 years, 8 months, 14 days old when hired by the Oakland Raiders in 2007.
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.
