Sam Darnold's NFL career has experienced a revival with the Minnesota Vikings, thanks to a well-designed scheme and elite protection. Under Head Coach Kevin O'Connell, the Vikings have focused on play action and motion to put their quarterback in position to succeed. The offense has also utilized pre-snap or at-the-snap motion on over half of their snaps. Moreover, the Vikings have devoted resources to keeping extra men in to block for Darnold, making it difficult for opponents to pressure him.
