Dolphins-Commanders joint practice report; stock up, down

Key Points:

• The Miami Dolphins struggled offensively and defensively during their joint practice with the Washington Commanders, with quarterback Malik Willis facing heavy pressure and the secondary missing key players due to injuries.
• Commanders quarterback Jayden Daniels effectively exploited the Dolphins' weakened secondary, connecting on several big plays including a 70-yard touchdown to WR Treylon Burks.
• Despite the challenges, Dolphins players like linebacker Jordyn Brooks and right tackle Austin Jackson praised the physicality and mindset shown during practice, though they acknowledged the need for improved execution.
• Rookie WR Caleb Douglas stood out positively with strong performances in drills and receiving plays, while the offensive line and secondary units were identified as areas needing significant improvement.
• The practice featured no major scuffles, and first-year Dolphins coach Jeff Hafley used the joint session to evaluate his team against external competition for the first time this preseason.
