BUFFALO – The 49ers just lost 35-10 to the Buffalo Bills. Now the 49ers sit alone in last place in the NFC West at 5-7. Here are her grades for this performance.

QUARTERBACK: F

Brock Purdy was terrible. He threw for just 94 yards, his quarterback rating was an abysmal 74.8, and he fumbled because the ball slipped out of his hand as he tried to throw it. This happens to him at least once every time he plays in the wet. That means he’s not a franchise quarterback. Franchise quarterbacks need to be able to play well in all conditions – see Josh Allen, whose quarterback rating was 141.3 tonight. He is a franchise quarterback. Purdy is a good story, a story that has reached its end. I’m not saying they need to get rid of Purdy, but they can’t extend his contract and need to find another quarterback this offseason. And Kirk Cousins ​​is not the answer.

RUNNING BACKS: A

Christian McCaffrey played well until he left the game with a PCL injury that could end his season. It turned out that the 49ers were way too aggressive with McCaffrey and should ease him back onto the field. There was no reason to overuse McCaffrey considering Jordan Mason averaged 6 yards per carry tonight and Isaac Guerendo scored a touchdown. These three should have been split up the entire time.

Full-back: F-MINUS-MINUS

Touched the ball once and fumbled at the goal line the season. Tragic.

WIDE RECEIVER: D

Jauan Jennings had three catches for 56 yards – one of the few players on the team who played his best every week. Meanwhile, Deebo Samuel had another terrible game – four catches for 20 yards. And Ricky Pearsall had no catches for the third game in a row. I’m starting to think he was the wrong choice in Round 1.

TIGHT ENDS: D

George Kittle blocked well but only caught one pass for 7 yards.

OFFENSIVE LINEMEN: C

They blocked very well in the run game despite the absence of Trent Williams and Aaron Banks, but they struggled in pass defense, as they have all season.

DEFENSIVE LINEMEN: F

They gave up 220 rushing yards and sacked Josh Allen a total of zero times. Pathetic.

LINEBACKER: F

Fred Warner recorded just four tackles as he tried to overcome cramps and a broken ankle. He’s a liability at the moment.

DEFENSE: F

They allowed two touchdown catches and missed a number of tackles in the run game. Ji’Ayir Brown is not a starting safety. The 49ers must replace him this offseason.

SPECIAL TEAMS: D

Jake Moody missed two field goals – he shouldn’t be on the team. Deebo Samuel had a 60-yard kickoff return, but he also fumbled a kickoff return and the Bills recovered. He shouldn’t be on the team either.

COACH: F-MINUS

For the second week in a row, Kyle Shanahan’s team did not compete. The players seemed to know they would lose. Shanahan’s game plan was terrible. He couldn’t get the ball to George Kittle, the best receiver on the team and one of the few players who still seems hungry. Shanahan has trained all season like someone who got a big extension last year and has nothing left to prove. It almost seems like he’s daring the 49ers to fire him – that’s how bad he was. And his players have followed his example. With the exception of Jordan Mason, Jauan Jennings and George Kittle, the 49ers have played like a team that has made a lot of money and has nothing left to prove. The 49ers need to clean up and get rid of all the people who are complacent and complacent. And that includes Shanahan. He is the most smug person on the team. And he ran out of fresh ideas years ago. Let’s see if the 49ers have the courage to do what needs to be done.
