The Seattle Seahawks got their biggest win of the season Monday night, handing the San Francisco 49ers their first defeat on a field goal as the clock expired in overtime. With the 27-24 victory, the Seahawks moved to 8-2 on the year and shaved the 49ers’ lead in the NFC West to a half-game. There was plenty to discuss after the matchup — good, bad and ugly abounded all night.

THE GOOD

Jadeveon Clowney: Clowney posted his best game as a Seahawk, welcoming 49ers tackles Joe Staley and Mike McGlinchey back from injuries by absolutely dominating them at the line of scrimmage and constantly getting into quarterback Jimmy Garoppolo’s face.

In all, Clowney posted a defensive stat line of five tackles, five QB hits, one sack and one forced fumble; he also scored Seattle’s first points by recovering another Garoppolo fumble and running it 10 yards into the end zone late in the second quarter. The Seahawks have had pass-rush issues recently, but if Clowney can regularly post this kind of performance, the unit should become much less of a liability.

The rest of the defense: New acquisition Quandre Diggs showed up in a big way at the safety position. His interception of Garoppolo in the third quarter led to the second Seahawks touchdown of the night. Linebacker Bobby Wagner was his usual self, totaling 11 tackles and one defended pass. Defensive tackle Al Woods added two tackles for loss (including one sack) and cornerback Shaquill Griffin continued his standout season with two defended passes and six total tackles.

On the night, the Seahawks sacked Garoppolo five times, in addition to completely shutting down the 49ers’ run game and forcing Garoppolo to throw a number of near-picks. It was a massive turnaround for the much-maligned defensive squad, which they hope to carry into their matchup against the Eagles in two weeks’ time.
