SEATTLE -- The Los Angeles Rams had a chance Thursday, despite the quick turnaround, the hostile environment and the sudden coaching change. They arrived in Seattle as 15 1/2-point underdogs, then dropped easy catches, missed wide-open throws, committed ill-timed penalties and let too many opposing receivers get free. By the end of it, they made outspoken Seahawks cornerback Richard Sherman seem prophetic.

Their play, in essence, was a "poopfest."

"The constant inconsistencies, it’s very frustrating," Rams left guard Rodger Saffold said. "It drives you crazy."

Three days after firing coach Jeff Fisher, the Rams looked even sloppier under special teams coordinator and interim coach John Fassel, suffering a 24-3 defeat to the division-rival Seahawks on a frigid Thursday night at CenturyLink Field. It snapped a three-game winning streak against Seattle and gave the Rams nine losses over a span of 10 games, dropping their record to 4-10. And it ended without their franchise quarterback.

With the game already out of reach and about nine minutes remaining, Goff ran 15 yards up the sideline, took the ball to the Seahawks' 2-yard line and did not get out of bounds before Sherman delivered a vicious blow. Goff's run was called back because of a hold by right guard Andrew Donnal, and Goff was promptly taken to the locker room under the NFL's concussion protocol, prompting former starter Case Keenum to take over.

Goff was deemed fine by several of his teammates, but the Rams suffered a litany of mistakes before he exited.

"It's discouraging," Fassel said. "The players are frustrated that the same things keep happening over and over."

It began with veteran tight end Lance Kendricks dropping an easy short pass to open the game and continued with rookie Mike Thomas, who fumbled the opening kickoff in a five-turnover game Sunday, dropping a deep pass while wide open downfield. Goff then threw way behind a wide-open Brian Quick in the end zone, a drive that finished with a turnover on downs when the Rams failed to convert a fourth-and-1 from the Seahawks' 7-yard line.

Fassel then called a fake punt despite being at his own 30-yard line and requiring nine yards for a first down, a play that resulted in a Johnny Hekker pass that was well underthrown. Defensive tackle Dominique Easley (roughing the passer) and middle linebacker Alec Ogletree (hold) committed key penalties that led to a Seahawks touchdown. Troy Hill, who missed four games after being disciplined for a DUI arrest, was beaten badly at the line of scrimmage by Doug Baldwin for another Seahawks touchdown.

Then there was the offensive line, which allowed four sacks and created constant pressure on Goff. Then there was Seahawks punter Jon Ryan, who was allowed to run 26 yards on a fake punt. And then there was Aaron Donald, encapsulating the Rams' season in one play -- when he was hit with a 15-yard penalty for a face mask, then another 15-yard penalty for throwing the official's flag.

The Rams, perpetually mediocre during their final four seasons in St. Louis, have quickly devolved into a laughingstock in their first season back in Los Angeles.

"Everybody in this room definitely had a reason why our head coach was fired," Rams receiver Tavon Austin said. "Individually, I wish I could’ve done more. Everybody wishes they could’ve done more. But 'wish' is not going to get it done. We have to finish these last two off. Hopefully nobody quits. I know I’m not going to quit. "
