The 49ers just lost 29-17 to the Miami Dolphins. Here are the 49ers' grades for this performance. QUARTERBACK: C Brock Purdy played well until the final two minutes of the game. That's when he needed to lead a touchdown drive in 2 minutes and 10 seconds with his team down by 5 points.

On Sunday, Samuel looked like his old self, breaking tackles, dragging defenders, and making critical plays while chipping in as a running back. Samuel had seven catches for 96 yards, a touchdown (his second receiving touchdown this season), and added 25 yards on the ground. He broke at least a dozen tackles, too.
