Stacked boxes: every call

Backs who hold up against eight or more in the box lose less against defenses that stack the box (negative split × high rate = penalty).

How this works

Win: a boost beats our projection mean, or a fade falls below it. Push: within 0.5 points. Void: did not play, or played under 25% of his usual snaps. Backtest calls use only data from before their week (the made time is 90 minutes before his kickoff); live calls are written before kickoff and cannot be edited afterwards. We list every loss. All angles and the method.
