Chiefs' preseason reveal: run-focused attack, backup QB hopes, and defensive flashes

The Chiefs opened their 2026 preseason with a 20-12 loss to the Rams but offered early signals: a possible run-first attack led by Emmett Johnson with Kenneth Walker III rested, Garrett Nussmeier showing potential as a backup QB despite rookie missteps, Mason Thomas delivering disruptive flashes on the defense, and receivers in the group largely quiet aside from Cyrus Allen while Jaden Hicks stood out with seven tackles as the team builds depth for the regular season.
