Broncos QB Bo Nix chalked the starting group’s sluggish preseason debut up to playing against mostly un-scouted looks and said there’s a lot to build off of.

The Broncos' second-year QB committed a penalty that resulted in a safety but ended night by leading a field-goal drive.

Jarrett Stidham threw two TD passes following a lackluster performance from Bo Nix and Denver's starters, and the Broncos beat the San Francisco 49ers 30-9 in the preseason opener Saturday night.
