QB Replacement & Passing Dynamics Simulator
When an NFL starter goes down, the entire offensive identity shifts. Compare Caleb Williams’ downfield creation window against Tyson Bagent’s quick-snap rhythm passing across play concepts and defensive schemes.

Understanding In-Game Quarterback Transitions
Why does the offensive gameplan contract when a backup enters?
When an offensive scheme loses its primary starter mid-game, coaches usually replace high-variance intermediate routes and extended five-step dropbacks with quick 3-step rhythm timing. Tyson Bagent excels in lightning-quick decision-making and pre-snap recognition (averaging under 2.3 seconds to release), which neutralizes aggressive defensive pass rushes while sacrificing deep outside-the-numbers shots.
How does the pocket timer in this simulator reflect real pass rushes?
NFL edge rushers consistently reach the quarterback within 2.4 to 3.0 seconds against 4-man rushes, and under 2.2 seconds during blitzes. If a user holds the ball past the QB's release threshold against Cover 0 or Cover 1, the pocket collapses into a sack or deflected throw.
Can this simulation data be exported for analytics study?
Yes. The “Export Drive Play-by-Play” button outputs a structured CSV with down, distance, play concept, defensive shell, intended air yards, time to throw, completion status, and computed EPA for each simulated snap.
