I can only assume that if a team plays no regular season games, they would be ineligible for the playoffs. If other teams in their district are not participating in a sport, and they have to find a game outside their district, I can't imagine that that would be in any way held against them. If they purposely did not schedule district games in lew of scheduling OOD opponents, then even in this crazy season, I think that excludes them from the playoffs.
Here is another adverse circumstance that could bring up issues. Suppose a team has multiple games canceled because of covid protocols? That certainly can't be held against them. Here is the real fly in the ointment, though. Suppose playing an incomplete six came schedule gives them a higher or lower power points rating and they make, or don't make, the playoffs because of the altered schedule. Someone is certain to have their feathers ruffled because of this.
Man, what a year.
