The 49ers dominated the Dallas Cowboys in their 42-10 win on "Sunday Night Football," which subsequently led to some interesting PFF grades.
San Francisco quarterback Brock Purdy earned an 85.3 overall grade after another stellar performance in which he completed 17 of 24 pass attempts for 252 yards and a career-high four touchdowns.
The quarterback’s intermediate throws from 10 to 19 yards downfield continue to be his sweet spot. Purdy connected on 5 of 7 intermediate attempts for 105 yards and two touchdowns. Through five games, Purdy is now 27 of 31 for 490 yards, four touchdowns and a perfect 158.3 rating on those passes.

Here are more highlights from the 49ers Week 5 PFF grades:

San Francisco 49ers
The 49ers' offense allowed 10 total pressures, and the offensive line was responsible for all but one. Otherwise, they offered solid protection for Purdy, who was on the field for 60 of the club’s 67 total offensive snaps. Fullback Kyle Juszczyk was responsible for the Cowboys' only quarterback sack in the game.
