49ers overmatched by defending NFC champion Panthers

What a difference a week makes.

Six days after shutting out the Los Angeles Rams, the San Francisco 49ers surrendered 46 points to the high-powered Carolina Panthers in a mostly uninspiring loss against the reigning NFC Champions.

San Francisco’s secondary was overmatched by big-bodied playmakers in QB Cam Newton‘s arsenal, as towering receivers TE Greg Olsen, Kelvin Benjamin and Devin Funchess accounted for all four of Carolina’s touchdowns on the day.

Add a lack of pressure by a San Francisco defensive front that tallied just three hits on Newton — including a forced fumble — and it’s easy to see why the Super Bowl runner-ups put up their most points in the regular season since 2011.

Not that the stumbling 49ers offense was of any help.

QB Blaine Gabbert had yet another erratic day under center, completing just 17-of-36 passes for 243 yards, two touchdowns and two interceptions. Gabbert would also rush for a one-yard score following an impressive special teams play by Shaun Draughn to recover a botched Ted Ginn Jr. kickoff.

The 49ers ground game offered no reprieve for Gabbert, forcing the quarterback to air it out in easily-defensible third-and-long situations after gaining just 65 total yards rushing on the day.

Torrey Smith and Vance McDonald were the lone bright spots for San Francisco’s offense, each hauling in impressive touchdowns on the day. McDonald’s 75-yard score was the longest of his career.

If one can find a bright side in such a disastrous showing, it’s that the 49ers defense continued to force turnovers with swarming tackles and hard hits.

The unit notched three turnovers, including two fumble recoveries and an interception, helping to keep their team in the game throughout a first half that ended with just a touchdown difference at 17-10.

That’s where the praise begins and ends for San Francisco, as the defense continued on to surrender a total 529 yards of offense to Carolina while being beat on all fronts on Sunday.

The biggest question for San Francisco heading into Sunday’s contest was whether or not their defense could repeat their stout effort against Newton and the high-powered Carolina offense.

It didn’t take long for the 49ers to attempt to answer that, as defensive leader NaVorro Bowman would tip a pass to S Antoine Bethea for an interception just two snaps into the game.

After a slew of consecutive run plays fell flat, K Phil Dawson would split the uprights for a 29-yard score to give the 49ers an unlikely 3-0 lead.

Not one to be overshadowed on the defensive end, Carolina would return the favor with their own forced turnover on the 49ers ensuing drive, as LB Shaq Thompson would plunge into the end zone after scooping up RB Carlos Hyde‘s first fumble of the season for a touchdown.

The defensive back-and-forth would continue with the 49ers coming up on the receiving end of a fumble after nickel back Chris Davis laid a heavy shot on Carolina running back Fozzy Whittaker to jar the bar loose.

Like their previous try, San Francisco would cash in on crucial points on the turnover, as WR Torrey Smith would make his first big contribution of the season with a 28-yard touchdown score working one-on-one against rookie CB James Bradberry.

In a raw and young defensive unit, the first 49ers mistake would come at the hands of the 11-year veteran Bethea, who didn’t pick up Pro Bowl tight end Olsen as he sprinted up the middle of the field for a 78-yard score.

The score by Olsen would not only give Carolina a 14-10 lead, but would mark the first touchdown surrendered by the 49ers defense on the season.

A leaky 49ers defense was unable to stop the Carolina run game all afternoon. Working the majority of the game without starting running back Jonathan Stewart, Carolina still managed to eat up 110 yards on the ground in the first half alone. Noticeably absent was pressure on Newton, who looked poised and collected running Carolina’s offense.

Carolina would head into the half a field goal richer after Newton led a quick drive down the field to get K Graham Gano into range as time expired in the first half of play.

As Gabbert’s grip on the 49ers offense started to slip, the reigning MVP Newton continued to gain traction in picking apart an overworked San Francisco defense.

The big-bodied Benjamin would start his second half explosion by picking on the smaller Jimmie Ward, who surrendered two consecutive catches to Benjamin for 35 yards and touchdown on the Panthers’ first drive of the third quarter.

Newton would continue to look downfield against the 49ers’ faltering coverage, finding the speedy Ted Ginn Jr. for a 52-yard pick up to start the ensuing drive. Newton followed his big gain with a 9-yard strike to Benjamin, who hung on to the ball despite being sandwiched between Ward and S Jaquiski Tartt.

Frustrations for the San Francisco offense came to a head in the fourth quarter, as the team couldn’t take advantage of a short-field opportunity following the defense’s third takeaway of the game.

After starting on the 17-yard line of Carolina following a fumble recovery by Eli Harold, San Francisco would lose four yards before settling for another Dawson field goal.

The 49ers’ full spectrum of offensive woes was on display during the three-snap sequence, as a short run, a misplaced throw by Gabbert and a sack provided a condensed summary of the conservative and ineffective offense.

San Francisco’s special teams came to the aid of a defense in need of rest, as a lazy attempt by Ginn Jr. to pick up a bouncing Dawson kickoff would be smothered by the 49ers’ Draughn on the one-yard line for a second-consecutive turnover.

Unlike the last try in Carolina territory, Gabbert would convert this opportunity himself, keeping the ball for a run up-the-gut and the 49ers’ first touchdown of the second half. The score would cut Carolina’s lead to 31-20.

Gabbert continued his resurgent effort following another Carolina field goal by connecting with McDonald for a 75-yard score after a hard downfield block by Quinton Patton would spring the tight end free for the longest touchdown of his career.

It would be downhill for Gabbert after that, tossing two interceptions on the ensuing drives that would lead to 10 additional Carolina points to seal the 49ers fate.
