3 instant takeaways from Chiefs’ Preseason Week 3

1. The Chiefs' defense has become much faster since rookie cornerback Mansoor Delane started playing with the starters in the previous preseason game, displaying outstanding speed to the point of contact.

2. Rookie defensive end R Mason Thomas is expected to significantly contribute to Kansas City's pass rush in 2026, thanks to his excellent speed and agility, particularly in disrupting the quarterback with his blindside sack.

3. Starting running back Brashard Smith and wide receiver Andrew Armstrong are proving their worth during the preseason, with Smith showcasing his speed in the return game and Armstrong leading the team in catches. Both players are unlikely to be cut from the roster after the cutdown day.
