here are the 49ers grades for their 32-19 win over the New York Jets Brock pie B plus he played his first career game without Christian mcaffrey and was solid spread the ball around to lots of different receivers avoided pressure made good decisions with the exception of one pass he forced into double coverage late in the game also threw a perfect pass to Brandon auk In The End Zone which auk simply dropped so P's numbers should have been better he's a very good quarterback who's beginning to prove that he's not a mere product of his all proo teammates running backs A+ Christian mcaffrey sat out with a sore achilles which means Jordan Mason started his first career game and carried the 49ers to Victory rushed 28 times for 147 yards in a touchdown the 49ers would not have won this game without him he adds a degree of power and violence to the Niners running game that they haven't had since Frank gour was in his prime if the Niners had used Mason more the past two seasons they might not have worn down mcaffrey at least Mason is fresh in addition fullback Kyle yusek had 40 receiving yards tonight which means the ners didn't miss a beat without mcaffrey wide receivers C+ Debo Samuel was overused he had eight carries for just 23 yards and a touchdown and the touchdown came on a Jet Sweep his runs when he lined up in the back field were ineffective he's not a running back as a receiver he caught five passes on nine targets for 54 yards which means he was okay nothing special but certainly better than Brandon auk who was extremely Rusty after sitting out the whole off season he caught just two passes on five targets for 28 yards is that what $30 million per season gets you these days he needs to play better Samuel does too because the 49ers best wide receiver since the playoffs has been Jawan Jennings tonight he led all 49ers with 64 receiving yards and he caught all five of his targets tight ends B plus George K had four catches for 40 yards and both he and Eric sober blocked exceptionally well in the Run game finally the Niners have a quality backup tight end offensive lineman C Colton mckivitz gave up a quarterback hit and committed two penalties he's by far the worst starting offensive tackle in the NFL and he's paid like it in addition Brendle got thrown on his back at least once the rest of this line was solid particularly rookie Right Guard Dominic puny Trent Williams left the game briefly to get an IV because he's not yet in Peak Physical shape but he returned to the game defensive lineman B they did an excellent job shutting down Jets running back Breeze Hall which is impressive considering run defense was an issue last season but the pass rush did not produce Leonard Floyd had one sack and Nick Bosa had two quarterback hits that's about it eventually the ners will need their pass rush to show up and do something linebackers B they did an excellent job without Dre Greenlaw Demetrius Flanigan fos even intercepted a pass that was tipped by dador Lenor those two linebackers played well dandre Campbell did not play particularly well he seemed slower than the other two defensive backs a dador Lenor tipped a pass that got intercepted and travarius Ward nearly picked off another pass those two remain an elite cornerback Duo Isaac yam also had a couple nice plays and Jer Brown and George odm both were fantastic in run support special teams a jake Moody made all six of his kicks he's automatic when there's no pressure coaches B+ Nick Sorenson immediately fixed a run defense that was mediocre at best last season give him credit for a good performance in his first game as a defensive coordinator he made quality adjustments and the players seemed play hard for him Kyle Shanahan also did a good job working around the absence of Christian mcaffrey and the rust of Brandon iuk and Trent Williams to be fair Shanahan called way too many plays for Samuel considering how well Mason Jennings KD and yuse cheek were all playing at times Shanahan seems borderline obsessed with Samuel even though other players are just as good or better than him still Shanahan found a way to win by 13 points if his team stays healthy it should make another deep playoff run this season n
