When linebacker De'Vondre Campbell casually mentions the Cardinals having a "virtual walkthrough," the term merits a follow up: How exactly does that even work?
It's new to the Cardinals — they had their first one this week — but it's also new in the overall sense of NFL teams finding ways to adapt in 2020.
