49ers 42, Cowboys 10: Grades

This is the 49ers' year.

SANTA CLARA -- The 49ers just humiliated the Dallas Cowboys 42-10 on national television. Here are the 49ers' grades:

BROCK PURDY: A-PLUS

The best performance of his career. He faced an outstanding defense with an elite pass rush and made it look tame. Threw for 252 yards, four touchdowns and no interceptions, and posted a passer rating of 144.4. Hardly played in the fourth quarter. Purdy continues to improve, which is surprising for a player with such a modest physical skill set. But his timing and confidence are off the charts. As long as he's healthy, the 49ers have a great chance to win the Super Bowl. This is their year.

RUNNING BACKS: B

The Cowboys made it their business to shut down Christian McCaffrey -- he scored a touchdown but averaged just 2.7 yards per carry. They did not make it their business however to shut down Jordan Mason, who averaged 6.9 yards per carry and also scored a touchdown. Mason is the perfect change-of-pace back for McCaffrey.

WIDE RECEIVERS: B

Both Brandon Aiyuk and Deebo Samuel gained more than 50 receiving yards. Even Jauan Jennings had a 19-yard catch. This is a good trio.

TIGHT ENDS: A-PLUS

George Kittle caught three passes and they all were touchdowns. He seems to play his best on national television. I can't imagine why.

OFFENSIVE LINEMEN: B

They gave up just one sack to the best pass rush in football and held Micah Parsons to zero sacks and zero quarterback hits, which is extremely impressive. Still, Trent Williams and Colton McKivitz each committed a false start penalty and Spencer Burford committed a hold. Bad Spencer.

DEFENSIVE LINEMEN: A

Completely overwhelmed the Cowboys offensive line and made Dak Prescott extremely uncomfortable all night (not hard to do to him). Nick Bosa and Arik Arsmtead shared a sack, and Kevin Givens had one plus a fumble recovery.

LINEBACKERS: A

They took advantage of the pressure created by the defensive line and made big plays. Fred Warner had eight tackles, 1 sack and 1 interception, Dre Greenlaw had 5 tackles, 1 sack and 2 tackles for loss and Oren Burks had five tackles and a pick.

DEFENSIVE BACKS: A

Held Dak Prescott to a passer rating of 51.6. Gave up just 153 yards through the air. Tashaun Gipson intercepted Prescott once, and Deommodore Lenoir tipped a pass that got intercepted by Fred Warner.

SPECIAL TEAMS: A.

Jake Moody still hasn't missed a kick in the regular season. Amazing considering how shaky he looked in the preseason.

COACHES: A-PLUS

Kyle Shanahan faced his old boss, Dan Quinn, and made him look completely inept. Shanahan attacked with so many players from so many different locations and made the Cowboys defense off balance and outnumbered at the point of attack. In the process, Shanahan found dozens of ways to neutralize Micah Parsons with multiple blockers -- no one had to block him one on one. Shanahan's game plan was masterful. And so was Steve Wilks' game plan, who made Cowboys head coach Mike McCarthy seem like a dinosaur. This is the best team the 49ers have had since Kyle Shanahan became the head coach -- not even close. This is their year to win the Super Bowl. Let's see if they do, because they should.
