What happened: Lamar Jackson and Baker Mayfield experienced the largest year-over-year declines in PFF passing grades last season. The shifts highlight significant changes in evaluation metrics across the league entering July training camps.

Why it matters: The grade trajectories align with recent metrics that ranked Dak Prescott eighth among NFL starters entering the upcoming campaign. Quarterback performance shifts remain a critical focus as coaching staffs solidify depth charts ahead of preseason competition. Stable production under center will dictate postseason contenders in a crowded playoff race.

What to watch: NFL training camps open later this month as teams prepare for preseason games in August. Coaching staffs will assess quarterback progression throughout live drills and exhibition matchups.
