Week 4
Brock Purdy is still first at +0.57 expected points added (EPA) per dropback, down from +0.66, after +9.9 on 33 dropbacks against the Broncos. Bryce Young had the week's biggest total: +21.0 on 45 dropbacks against the Lions took him from 14th to ninth. Drake Maye went from 29th to 22nd on +15.9 in 43 dropbacks at Buffalo, and C.J. Stroud from 23rd to 18th on +15.9 in 33 against the Cowboys. Lamar Jackson went from fourth to third after +12.0 on 23 dropbacks against the Titans, and Jared Goff from 10th to eighth on +12.3 against the Panthers. Jacoby Brissett had the week's worst, -18.0 on 39 dropbacks against the Giants, and went from 16th to 25th; Daniel Jones's -13.4 against the Commanders left him 33rd. Jaxson Dart, second a week ago, no longer qualifies: Jameis Winston took the Giants' dropbacks and the floor is now 48. 34 quarterbacks clear it and 22 are above zero. Nine of last week's top ten are still in it, though Drew Lock and Caleb Williams are second and fourth without a dropback this week. The top means something at 122 dropbacks for Purdy; the middle, where 0.15 separates 11th from 20th, does not yet.
Week 3
Brock Purdy is still first at plus 0.66 expected points added per dropback, up from plus 0.56, after plus 25.2 against the Cardinals on 28 dropbacks: his second straight game above plus 25. Lamar Jackson went from ninth to fourth on plus 12.6 in 22 dropbacks against the Cowboys, Joe Burrow went from 23rd to 15th on plus 15.1 against the Steelers, and Patrick Mahomes enters the top ten at ninth after plus 12.3 against the Dolphins. Josh Allen went from third to fifth, plus 0.53 to plus 0.34, after minus 3.5 against the Chargers. Monday night against the Bears took Jalen Hurts from 14th to 24th: minus 14.1 on 30 dropbacks, plus 0.18 to minus 0.01. The floor is 36 dropbacks, 36 quarterbacks clear it, and 22 are above zero. Nine of last week's top ten are still in it; Bryce Young went from seventh to 14th after minus 5.8 against the Browns. Jaxson Dart is second on 38 dropbacks, two games in; Purdy has 89. The top means something; the middle, where 0.13 separates 11th from 20th, does not yet.
Week 2
Brock Purdy went from 11th to first at plus 0.56 expected points added per dropback, with the largest single game any quarterback on this board has had through two weeks: plus 26.4 expected points on 25 dropbacks, 1.06 apiece. Josh Allen is third at plus 0.53 with the highest total on the board through two weeks, plus 37.7. Jaxson Dart is still second at plus 0.55 per dropback; only five of his 38 dropbacks came Monday night before he left the Rams game, and Jameis Winston took the other 29 and enters at 32nd of 33 with minus 16.5 expected points. Trevor Lawrence led this board after Week 1 at plus 0.79; a Week 2 worth minus 4.1 on 31 dropbacks has him eighth at plus 0.27. The floor is 24 dropbacks, 33 quarterbacks clear it, and 21 are above zero. Eight of last week's top ten are still in the top ten, because sixty dropbacks is a sample in a way twenty carries is not. This board settles faster than the rushing ones, but two games is still two.
