Given the aggressive approach so far by the NFL, I now believe they will carry on with the season no matter what

Right now I would not make any announcement but prepare for the worst that it will be postpone or even cancel. Too many people involve to have an NFL game played. 70 players, plus 10 coaches or whatever numbers it is. Doctors, trainers, refs, and the list goes on. Even without fans, the risk is still too high.
