Well, credit to them for trying, but I have my doubts these ideas would work.
For one, I believe some analysts have mentioned that in order to conduct daily testing on all players and also staff members who are close with the team, they'd need at least 10,000-15,000 tests per day. I don't even think there are many states testing more than 7,500 per day in healthcare networks, etc. So would they prioritize NBA players/staff over hospitals and other medical facilities? Good luck dealing with that outcry.
And two, what happens if someone like Giannis or Lebron end up testing positive and then isolate. How on earth is that fair for teams if their superstar players are unavailable while they are for other teams? Oh, and this isn't like if they find one player that tests positive, then they can automatically assume they're "on top" of the situation and that everyone else is fine. Nope, it'll likely spread.
Another thing I realized is, if you're on a bad team that's not making the playoffs anyways, then would you really want to return and put yourselves or even your families at risk?? I honestly doubt it. The primary folks pushing for a season resumption are those teams in the playoffs.
It's the daily testing + still playing if one player comes down positive parts that really perplexes me though. Gobert tested positive, then the NBA suspended the season, and we found out Mitchell was positive and then quite a few other players/staff of teams who had played the Jazz fairly recently tested positive and/or came down sick later on. Doesn't take a genius to realize that could happen again...
