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, according to sources.

The deal comes a little over a month since Stafford led the Rams to a 23-20 Super Bowl 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 arrived 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.

The quarterback guided the Rams to their first championship since Kurt Warner did so in 1999 while the team was based in St. Louis.
