What happened: Brock Purdy currently holds a league-best 0.0% pressure-to-sack rate, having avoided a sack on all 15 of his pressured dropbacks this season. Jayden Daniels ranks second at 4.2%, with one sack on 24 pressures.

Why it matters: Purdy's ability to extend plays and avoid negative yardage continues to validate his standing, after PFF named Brock Purdy the most valuable non-first-round pick since 2016. The metric emphasizes pocket awareness and the capacity to throw the ball away rather than absorb a loss.

What to watch: Purdy will look to maintain his clean sheet under pressure as the regular season continues.
