What happened: PFF charted Williams under duress on almost half of his dropbacks. The rate points to early pass-protection strain around Chicago's dropback game.

Why it matters: Chicago built its opening production around Williams after his 345-yard Week 1 lead. Continued pressure limits timing and downfield creation, and keeps backup readiness relevant after Tyson Bagent replaced an injured Williams.

What to watch: Watch Chicago's protection adjustments and Williams' availability heading into Week 3.
