How PFF graded Purdy, 49ers in Sunday's win vs. Cardinals

NBC Universal, Inc.

It was a hero’s homecoming both on and off the field for Brock Purdy in the 49ers' 45-29 win in the desert on Sunday. 

The Arizona native received an 86.5 overall PFF grade, bringing his six-week average to a league-leading 92.2 over that span, including a passer rating of 140.4. It wasn't easy as Purdy’s performance was not without pressure from the Cardinals' defense.

The quarterback completed eight of his 10 pass attempts for 138 yards, two touchdowns and a highest possible 158.3 passer rating when under pressure. When blitzed, Purdy was just as good, completing all four of his attempts for 60 yards and a touchdown.

Purdy continues to leave no doubt about his arm strength with an average depth of target at 13.5 yards, which is a career-high. The Iowa State product literally spread the ball around the field with only six of his 24 throws between the numbers. Fifteen attempts went to the left, while three went right (spike not included).

Coach Kyle Shanahan has been very impressed by his quarterback’s vision during the game.

“That he can see the whole field and there is nothing that he can’t do,” Shanahan said after the game. “He has a poise out there, you can see it. He can react. When he doesn’t have the time for stuff, he reacts and finds a way to check down and try not to take a sack or he creates and gets someone off-schedule.

“He’s had a great command over the offense just running it, but also the amount of plays he’s made throughout these two years has been as many plays of any quarterback I have ever been around with how much he does.”

Here are the highlights from the 49ers' Week 15 PFF grades:

WR Deebo Samuel - 78.5

Samuel caught four of his seven targets for 48 yards and two touchdowns, three of which were either first downs or touchdowns. Samuel only carried the ball one time for 11 yards, but forced three tackles. 

WR Brandon Aiyuk - 80.2

Aiyuk may have only caught three passes for 37 yards but his run-blocking continued to be a game-changer for the offense. The wideout’s 95.0 run-blocking grade topped the offense with Jon Feliciano (91.4) and Jauan Jennings (90.3) close behind.

Aiyuk and Jennings are the top-graded run-blocking receivers in the league according to PFF analytics.

Ward did not allow a catch on four targets giving Cardinals quarterback Kyler Murray a 0.0 rating when targeting Ward. The veteran cornerback also snagged two interceptions, returning one for a touchdown.

LB Fred Warner - 85.5

The linebacker recorded six total stops, and allowed only three completions on five targets for negative six yards and forced a fumble. Warner uncharacteristically missed three tackles on the day of the 16 missed by the defense.

CB Deommodore Lenoir - 84.0

Lenoir racked up eight total tackles — one missed. The cornerback also recorded three stops and allowed four catches on seven targets for only 36 yards.
