The 49ers went 80 yards on four plays, then came back with a five-play, 77-yard drive.There were solid performances all around, as a team that entered the game averaging a league-worst 213.7 total yards through three games erupted for 442 yards and 21-second half points.Here's a player-by-player look at the 49ers' offensive performance:
