What happened: Troy Renck identified middle-of-field execution as the key area for Nix to improve. Alex Singleton said the quarterback is operating like a 10-year veteran in Broncos camp and has increasingly used no-look throws.

Why it matters: Nix returned for his 2026 preseason debut after Denver reached last season’s AFC title game. More consistent production against zone defenses would leave fewer openings for opponents to restrict the offense’s passing lanes.

What to watch: Regular-season defenses will test whether the deeper preseason approach translates against sustained zone coverage. Throws between the numbers will provide the clearest measure.
