The San Francisco 49ers have one of the best offensive linemen in Trent Williams. Additionally, the 49ers do not have a great offensive line.
These two statements are not mutually exclusive.
According to PFF, Brock Purdy was under pressure on 39% of dropbacks this season. Not terrible, but significantly above the league average.
Purdy and the 49ers still excel against the blitz and lead the league with an EPA/game of 0.42 against the blitz per Sommersport. However, PFF notes that Purdy’s turnover-worthy play rate increases under pressure.
McKivitz and the rest of the team will be crucial in keeping San Francisco in this game, as Kansas City will be after the second-year quarterback. The Chiefs‘ defense is one of the best in the league at reaching the quarterback. Their pressure rate of 29.2% and blitz rate of 31.7% ranked second and sixth in the league, according to Sumer Sports.
