What happened: The qualifying mark is 70-plus dropbacks in the 2026 regular season. Dak Prescott, Patrick Mahomes and Trevor Lawrence round out the top four on the protection leaderboard.
Why it matters: Staying clean keeps drives on schedule and limits negative plays in September. Early separation on the sack board reflects line play as much as quarterback decision-making.
By the numbers: Brock Purdy 0 sacks; Dak Prescott 3; Patrick Mahomes 4; Trevor Lawrence 4 (min. 70 dropbacks).
What to watch: Watch whether Purdy's clean sheet holds as Week 3 closes and dropback volume climbs.
