Stock report after the 49ers’ loss to the Seahawks

Another week, another embarrassing loss for the San Francisco 49ers — this time falling 43-16 on the road to the Seattle Seahawks. The last time the 49ers traveled to CenturyLink Field and left victorious was Christmas Eve of 2011. Sunday was San Francisco’s eighth straight loss in Seattle, complete with the turnovers, penalties and missed assignments that we’ve come to expect from the now 2-10 team.

Here’s our stock report after the 49ers’ embarrassing loss to the Seahawks on Sunday:

Stock up: WR Dante Pettis

The 49ers’ second-round pick has capitalized on the absence of receivers Pierre Garçon and Marquise Goodwin. Over the last three games, Pettis has reeled in 13 receptions for 218 yards and three touchdowns. Pettis torched the Seahawks’ secondary for five catches, 129 yards, and two touchdowns Sunday in the rookie’s best game of the season. He may have gotten off to a slow start this season, but Pettis’ stock has never been higher.

Stock down: S Jaquiski Tartt

The 49ers’ starting safety has been ruled out of the team’s Week 14 matchup against the Denver Broncos at Levi’s Stadium. Tartt has battled a shoulder injury throughout the season that he aggravated Sunday while tackling Seahawks return specialist Tyler Lockett. Sunday will be Tartt’s sixth missed game of 2018 after appearing in nine last season before suffering a season-ending broken forearm.

Stock up: RB Jeff Wilson Jr.

In his Week 12 debut, Wilson rushed seven times for 33 yards and caught one pass for eight yards against the Tampa Bay Buccaneers. He followed that up with another solid performance against the Seahawks, carrying the ball 15 times for 61 yards and eight catches for 73 yards. Wilson had a controversial fumble, appearing to be down before the ball came loose. With lead back Matt Breida ruled out for Week 14, the 49ers will be relying on another stellar performance from the rookie undrafted free agent against the Broncos.

Stock down: QB Nick Mullens

Mullens’ fourth start for the 49ers wasn’t his worst, but it still came flawed with backbreaking turnovers. The third-string quarterback turned starter completed 30 of 48 passes (62.5%) for a whopping 414 yards, two touchdowns and a goal line interception returned for a 98-yard score by Seahawks linebacker Bobby Wagner. In addition to a pick-six, Mullens added a fumble in the end zone during a two-point conversion attempt. Shanahan said Monday that Mullens will start in Week 14 against the Broncos.

Stock up: DL DeForest Buckner

The 49ers’ defense was beaten up and down the field by quarterback Russell Wilson and the Seahawks’ offense. Despite the collapse, Buckner still managed to have himself a game. The 49ers’ star defender totaled seven tackles, two sacks, two quarterback hits, and two tackles for loss. Buckner’s nine sacks on the season, a personal best, matches his previous two seasons combined.

Stock down: CB K’Waun Williams

Williams was victimized Sunday against the Seahawks in both the run and pass game. The 49ers cornerback surrendered two end zone penalties, both of which resulted in touchdowns for the Seahawks. In another play, the Seahawks ran right at Williams, who was easily blocked out of the play — paving the way for running back Rashard Penny’s 20-yard score. It was particularly rough outing for the 49ers’ nickel cornerback.
