There is a fine line between making sure the fans are getting the fun they deserve and making sure that NBA doesn't pay a huge penalty and make sure that contracts suddenly doesn't drop because cap will have to be lower due to lack of money NBA teams made etc etc, but also putting lifes in danger.
When you are putting players in Las Vegas and making them play there to finish the league, you are not just putting players there, you are putting coaches, assistant coaches, floor moppers, broadcasters, doctors and many other people there as well, even if there is nobody watching live there in the arena. This is why I think it is quite risky. Could it be done? Sure it could be, but is it really the solution we are looking for? It feels like it wouldn't be fun at all and just would be "lets get this over with already" type of situation which doesn't really worth all the risks involved if you ask me.
I got the picture you are pointing out and it makes sense.
However, the plan will not be executed right away. It still depends on the situation that's why they take the plan to the month of July which is 3 months to go. In a span of 3 months, we can somehow expect that the USA or any country now finds a way now to minimize the infection and able to control it. And it's not as simple as
"come on resume the game now" as surely every precaution, safety, and all important things will surely take place. They will not push for something that is unprepared and empty-handed.
The world will not allow the virus to halt everything in a span of several months. Every country is doing its job. I strongly believed that the situation today will now be different 2 to 3 months from now. Just
"trust the process".
