49ers want pressure from defensive line full of first-round picks

After playing in their first two games, Jacksonville defensive end Calais Campbell led the NFL with four sacks and Dallas' Demarcus Lawrence had 3.5. The 49ers? They have three sacks. As a team. After three games. Yes, the pass rush has been a problem. "It wasn't good enough, you know?" head coach Kyle Shanahan said. Shanahan offered that Friday, a day after the 49ers didn't muster a sack in a 41-39 loss to the Rams. The lack of pressure meant quarterback Jared Goff finished with a clean uniform and stunning stats: In his 10th career start, Goff had career highs in completion percentage (78.6) and passer rating (145.8) and matched a career best with three touchdowns.
