Not quite that straightforward. Coronavirus fatality rate varies depending on age and if one has existing conditions.
14.8% if you're 80+
8% if you're in your 70's
3.6% in 60's
1.3% in 50's
0.4% in 40's
and 0.2% for 10-39
and no fatalities for children 0-9 recorded.
Those with comorbidities have a 7-13.2% death rate, however pre-existing medical conditions also tend to be more common among the aged.
One more factor that hasn't really hit the numbers yet given the small sample is the effect of medical responsiveness & capability of the regions who have seen the most cases.
China with 80k cases and 2.9k deaths has a 3.63% overall fatality rate. (again w/o knowing the demographics of the affected areas we wouldn't be able to draw any conclusions. e.g. maybe Wuhan has a higher percentage of older people. Maybe their medical care isn't as good as say, South Korea or the US.)
South Korea has 4.2k cases and 22 deaths or .5% overall fatality rate.
Anyway, my 2 cents is based on these figures and the ages of the athletes, NBA players have what looks like a 0.2% chance of dying from coronavirus.
One solution might be for the league to recommend those in attendance over the age of 50 to wear a mask and wash their hands before eating or touching their eyes.
