Brock Purdy's 49ers had a poor joint practice with the Chargers, indicating potential issues with their offense.
For fantasy purposes, this shouldn't move Purdy's draft stock in any meaningful way right now. Joint practices are notoriously unreliable indicators — they can reflect defensive scheme installs, backup reps, or simply an off day rather than any real erosion in Purdy's supporting cast or arm talent. Until you see corroborating reports about specific personnel issues (offensive line trouble, receiver injuries, or scheme concerns from beat reporters with higher confidence), treat this as background noise rather than actionable intel.
Action-wise: no change. Keep Purdy in his current tier on your board — he remains a quality QB1/high-upside QB2 target based on his track record and the weapons around him (Deebo Samuel Sr., Brandon Aiyuk, George Kittle, Christian McCaffrey when relevant). Don't downgrade him or push him down draft boards off one practice report. If you're doing scouting for redraft or dynasty, keep an eye out for follow-up reporting through the rest of preseason — specifically whether this becomes a pattern in joint practices or preseason games — before you let it influence your rankings. Confidence in this specific news item affecting his actual fantasy outlook: low.
The 49ers' offense wasn't up to par in their joint practice against the Chargers' defense on Tuesday.
