The Los Angeles Rams have made Sean McVay the youngest head coach in NFL history.
McVay was officially appointed by the Rams on Thursday, his hiring the latest step in a remarkably quick rise for the 30-year-old, who had previously served as the Washington Redskins offensive coordinator for three seasons.
He was originally promoted to Washington's coordinator position after serving as their tight ends coach for three seasons (2011-2013) and spending one as an offensive assistant (2010).
"This is an exciting day for the Los Angeles Rams as we welcome Sean McVay as our new head coach," Rams owner Stan Kroenke said in a statement.
"The accomplishments and success that he has rendered in less than a decade in our league are remarkable. I am confident in his vision to make this team a consistent winner and to ultimately bring a Super Bowl title home to Los Angeles."
"I am incredibly honoured by this opportunity and I want to start by thanking Mr. Kroenke and [executive vice president of football operations] Kevin Demoff for their faith in me to lead the Los Angeles Rams as head coach," McVay said.
"Collectively, we are committed to building a championship calibre team, and I'm excited to start that process and make our fans proud."
Under McVay's stewardship, the 2016 Redskins offense became the first in franchise history to average more than 400 yards per game in a single season.
Lane Kiffin, who was was four months shy of his 32nd birthday when the Oakland Raiders hired him in 2007, was the previous youngest head coach in the history of the league.
Rams defensive end William Hayes is 31 and older than McVay, who will not turn 31 until January 24.
But, as a plus for McVay, the Rams have fielded the NFL's youngest roster for each of the last five years.
