How PFF graded Purdy, 49ers in epic collapse vs. Rams originally appeared on NBC Sports Bay Area
It was all going well for the 49ers until it wasn’t.
San Francisco’s collapse in its 27-24 loss to the Los Angeles Rams on Sunday at SoFi Stadium included a myriad of mistakes in all three phases of the game, but a few key players’ performances 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 top-graded players on the day. Jennings had a career day stepping up in the passing game as Purdy’s No. 1 target. The Tennessee product caught nearly everything thrown his way, hauling in 11 of his 12 targets for 175 receiving yards and a whopping three touchdowns.
As a result, Purdy’s statistics also were impressive, completing 22 of his 30 attempts for 292 yards, three touchdowns and a 137.1 rating.
Multiple 49ers defenders had strong performances but the defense as a whole made enough mistakes to allow Rams quarterback Matthew Stafford to move the ball effectively down the field, completing 16 of his 25 attempts for 221 yards and a touchdown.
The 49ers had no answer for Rams running back Kyren Williams. who amassed 116 total yards from scrimmage — 89 on the ground — and three total touchdowns. Wide receiver Tutu Atwell nearly hit the century mark with four catches on five targets for 93 yards.

Coach Kyle Shanahan called for more play action than in Minneapolis and Purdy took advantage, completing a perfect eight of eight for 127 yards and one touchdown with a 158.3 passer rating.
