The Los Angeles Rams famously hired Sean McVay to become their head coach when he was just 30 years old, making him the youngest NFL head coach in the Super Bowl era. There were skeptics about his age when he was initially hired, but those were quickly swept away as McVay transformed the Rams into a contender and immediately caught the NFL's notice with his offensive schemes.
The Rams' hiring of McVay proved wildly successful. He won Coach of the Year after his rookie season, led them to the Super Bowl in just his second season, and then won the Lombardi Trophy in his fifth season. Though the Rams have achieved the ultimate feats with McVay as head coach, general manager Les Snead says he jokes to McVay that they both changed and "ruined" his life by hiring him at such a young age.
