On a day when LA's newest football team — the Chargers — stole most NFL headlines, the Los Angeles Rams made a big announcement of their own.

The team hired 30-year-old Sean McVay as their new head coach, the youngest in NFL history.

McVay, who turns 31 in a couple weeks, barely surpasses Alabama head coach Lane Kiffin as the youngest NFL head coach to date. Kiffin was 31 when the Raiders hired him in 2007.

McVay replaces Jeff Fisher, whom the Rams fired midway through their first season back in Los Angeles, where the team played from 1946-1994. Here's a little perspective on the difference between Fisher and McVay.

The Rams new head coach will be tasked with improving on the Rams' dismal 4-12 record in 2016. That's a daunting assignment, especially for a 30-year-old.
