Nobody has debated (yet) what should happen. But it’s certainly plausible (therefore not absurd) for someone to think that half a season or less will be played. (Personally I just think it’s too early to guess.)
We could have (and should have) played 80 games in 2020, so to think they won't greatly exceed that in 2021 seems unreasonable considering we have a vaccine now. Not to mention, the fans just won't tolerate it.
