Isn’t it strange no new Covid cases?

I think some coaches will tell their teams they have to be extra cautious this year. If we were in the hunt, I'm sure Payton would warn players about locking down their households (if you don't live here you can't come in my house, mask protocols, etc.).
Absolutely. And that is the coach's job. To make sure their players are ready to play. And that certainly means coaches will require players to protect themselves at all costs during the playoffs. So, that emphasis would probably help in reducing the number of players across the league getting infected, along with the reduced vectors for spread discussed earlier.
