Brock Purdy had a mixed performance in the 49ers' recent victory over the Patriots, completing 15 of 27 passes for 288 yards, one touchdown, and one interception. Despite the team's overall success, Purdy's completion percentage was lower than his career average, likely affected by back soreness. Looking ahead, he remains a strong fantasy option as the team prepares for another favorable matchup against the Cardinals.

• Purdy's performance was impacted by back soreness.
• Despite modest numbers, he is still a viable fantasy option.
• The 49ers are facing injury challenges with key offensive players.
