Dolphins will provide a much different test than the Cards' short yardage pass game with Kyler Murray extending everything.
Tua is just as accurate as Kyler, but he doesn't remotely have Murray's mobility. But obviously the Phins with Hill and Waddle and Achane have like exponentially more speed and can obviously attack the team downfield. That can play to McDermott's defensive strength in terms of scheming & layering coverages, especially with Groot and Von being better than last season.
Offensively my expectation is for the Bills offense to have its way with the Dolphins defense
