How PFF graded Purdy and the 49ers in their epic collapse against the Rams originally appeared on NBC Sports Bay Area
Everything was going well for the 49ers until it didn’t.
San Francisco’s collapse in a 27-24 loss to the Los Angeles Rams on Sunday at SoFi Stadium was marked by a multitude of errors in all three phases of the game, but the performance of several key players kept the club in the lead until the final two seconds of the game.
Quarterback Brock Purdy and wide receiver Jauan Jennings were PFF’s highest-graded players on the day. Jennings had a career day, becoming Purdy’s No. 1 target in the passing game. The Tennessee product caught nearly everything thrown to him, catching 11 of his 12 targeted passes for 175 receiving yards and a whopping three touchdowns.
As a result, Purdy’s stats were also impressive: he completed 22 of his 30 attempts for 292 yards, three touchdowns and a rating of 137.1.
Several 49ers defenders performed strongly, but the defense as a whole made enough mistakes to allow Rams quarterback Matthew Stafford to move the ball down the field effectively, completing 16 of his 25 attempts for 221 yards and a touchdown.
The 49ers had no answer for Rams running back Kyren Williams, who totaled 116 yards from the offensive line – 89 of them on the ground – and three touchdowns. Wide receiver Tutu Atwell almost reached the 100 mark with four catches on five attempts for 93 yards.
Here are the 49ers’ PFF grades for Week 3:

Coach Kyle Shanahan called for more plays than in Minneapolis and Purdy took advantage, completing a perfect eight of eight passes for 127 yards and a touchdown with a passer rating of 158.3.
Purdy’s strength continues to be intermediate throws from 10 to 19 yards, where he completed nine of his 11 attempts for 156 yards and two touchdowns, helping to achieve an NFL-leading 86.2 percent success rate on those passes through the first three weeks.
