49ers game grades from seemingly dominant Week 4 win over Cardinals

49ers Offensive Grades

What has become a new (and welcome) sight for the 49ers is their offense picking up the defense in tough situations. On Sunday, the Niners were nearly perfect on offense, which kept the game from ever escaping their grasp.

RB Christian McCaffrey

This is a little blurb to marvel over San Francisco's trade acquisition from last year, which has completely unlocked the offense to an efficiency level almost impossibly seen.

Christan McCaffrey not only continued his streak of a touchdown in games played, but he finished with FOUR touchdowns. Read that again, four touchdowns.

By himself, McCaffrey outscored nearly half the teams in the NFL this week. His touchdowns came in a variety of ways: outside runs, receptions, inside runs from the goal line.

McCaffrey is the star of an offense with more talent than needed, and when he is on, the 49ers are nigh unstoppable. What an incredible player.

Grade: A+++

49ers Rushing Offense

As you may guess from McCaffrey's dominance, the Niners had a good day on the ground. But despite their star running back topping 100 yards for the game, the offense did not move through the ground. They finished with 124 yards on 31 carries (including sneaks, kneel-downs, etc.), and both Jordan Mason and Deebo Samuel were largely ineffective rushing.

But McCaffrey was more than good enough to carry the unit, and there are no negatives to point out from a team that ran the ball at a 4.0 yards-per-carry clip.

That's efficiency that'll win games.

Grade: A

49ers Passing Offense

McCaffrey overshadowed what might have Brock Purdy's cleanest game. Purdy finished with 283 yards on a 20-of-21 line, which was the highest completion percentage of any 49ers quarterback with over 20 attempts. A team boasting Hall of Famers like Joe Montana and Steve Young, and Brock Purdy sits atop the franchise leaderboard.

Purdy didn't play it conservatively either. His play was an aggressive intermediate and downfield passing attack.

The biggest beneficiary was Brandon Aiyuk, who returned from injury and casually put up 148 receiving yards. McCaffrey was the next-highest receiver with 71 yards of his own. And there wasn't a bad throw among them, nor a poor read, nor a broken play.

The 49ers offense was essentially perfect, and Deebo Samuel, the star of Thursday Night Football, did not even record a reception.

Grade: A+
