The Rams and Matthew Stafford have finalized a four-year, $160 million extension that includes $135 million guaranteed that should allow the veteran quarterback to finish his career in Los Angeles, sources tell ESPN’s Adam Schefter.

The deal comes a little over a month since Stafford lead the Rams to a 23-20 Super Bowl LVI win over the Cincinnati Bengals at SoFi Stadium to complete one of the most impressive first-year runs by a quarterback in recent NFL history. After a dozen years in Detroit, Stafford proved to be the solution to most of the Rams’ offensive problems after he landed last spring with Sean McVay, Cooper Kupp and the teammates who have ridden his steady, effective play to their second Super Bowl appearance in four seasons.

In maintaining a steady focus and sturdy leadership throughout the Rams’ season, the 33-year-old quarterback guided the Rams to their first championship since Kurt Warner did so in 1999 while the team was based in St. Louis.
