SEATTLE — Jared Goff, Todd Gurley and the rest of the Los Angeles Rams who will make up the foundation of the franchise as it moves forward from a tumultuous first season back in Southern California got an up-close look Thursday night at what they eventually must overcome.

Even with all its flaws, Seattle remains the class of the NFC West.

The Seahawks clinched their third division title in the past four seasons with a 24-3 win over the Rams, adding another setback to an already lost season for Los Angeles. It was the capper to a crazy week for the Rams that started with the firing of head coach Jeff Fisher and concluded with a fifth straight loss.

And while interim coach John Fassel soaked up his first opportunity to be an NFL head coach — with his dad, former NFL coach Jim Fassel, in attendance — he also was witness to the same mistakes that have led to a miserable season for his team.

Los Angeles botched early opportunities to put a scare into the Seahawks, including Michael Thomas dropping a potential touchdown and Goff throwing behind wide-open Brian Quick in the end zone.

One play after Goff and Quick couldn’t connect, Gurley was stopped on fourth down. .

“Obviously, losing was disappointing,” Fassel said. “But standing out in the stadium and my dad was on the sideline and just looking around at the stands — how quickly things change in basically 72 hours. From Monday morning to Thursday afternoon. It’s just a lesson for me that you always have to be ready to adapt and take on responsibilities that you didn’t anticipate.”

Seattle was able to wrap up the division thanks mostly to a bounce-back effort from Russell Wilson. He threw for 229 yards and three touchdowns, hitting Luke Willson on an 8-yard score, finding Doug Baldwin on a 1-yard TD late in the third quarter and the capper a 57-yard strike to Tyler Lockett in the fourth quarter.
