The San Francisco 49ers’ first-team offense shined during their third preseason game against the Minnesota Vikings. We break down the film of the 49ers’ first offensive drive of the game.

Shanahan had his offense — which Bleacher Report recently ranked as the best offensive scheme in the NFL — running on all cylinders with his starting squad. Since the third game of the preseason is generally used as a “dress rehearsal” for opening day, the 49ers’ offensive outbreak came at the perfect time.

Let’s take a look at how the 49ers’ starting offense drove down the field for the five-play score. After stopping the Minnesota Vikings on their opening drive, the Niners began their first offensive drive on their 21-yard line.
