What happened: Drake Thomas sits second on the list at 18.2%, followed by Kaden Elliss at 16.0%. Daiyan Henley is at 15.4%, with Fred Warner and Roquan Smith tied at 14.3%.

Why it matters: Knockdowns offer an early read on how often linebackers are affecting quarterbacks even when the play does not end as a sack. Dean already showed up atop PFF's linebacker pass-rush grades earlier Saturday, so this ranking points to the same pressure impact from a second measure.

What to watch: Watch whether Dean can hold that margin as the sample grows over the next few weeks and the rest of the leaderboard gets more pass-rush volume.
