The San Francisco 49ers success this season hasn’t been flashy, and that’s not a coincidence. The 49ers style of play is old school on both sides of the ball. In an era where quarterbacks can throw up to 60 times a game, the 49ers are the first team in a decade to have over 300 rushing attempts in the first half of a season. SI’s Robin Lundberg highlights the 49ers change from the west coast offense that former Hall of Fame 49ers coach Bill Walsh invented, to the ground and pound style the has led San Fran to an 8-1 record.
