One of the biggest flaws of the San Francisco 49ers entering this season is their pass rush. The team had only 30 sacks last year which was 26th in the league. Even worse, 6.5 of those sacks — or over 20 percent — came from EDGE Elvis Dumervil, who the 49ers released in the offseason.
If you prefer advanced metrics, the Niners ranked 29th in adjusted sack rate, per Football Outsiders. Adjusted sack rate is the percentage of sacks per pass attempt. The league averaged 6.7 percent, whereas the 49ers were at 5.
