What happened: Bo Nix enters Year 3 as the focal point of Denver's training-camp outlook. He returned to practice during June minicamp after recovering from a broken right ankle.

Why it matters: His development will shape whether Denver can build on last season's run to the AFC title game. Camp shifts the focus from rehabilitation to his execution and mobility.

What to watch: Denver's first open practice is July 31, providing the first public checkpoint for Nix's workload. The regular-season opener follows Sept. 14.
