I think you will have to revise your season start date. I sincerely doubt it starts on time. I don't think there will be a preseason and I think they will move the season start back by 2-4 weeks. They want to play an entire 16 game season but I have my doubts. I think they will be lucky to play a 14 game season by simply cancelling the first two weeks and moving the rest back by 2 weeks. That would allow them to start in October.
Look at what's happening in FL, TX, AZ, and CA. I don't see those states being ready by September. A UK synthetic vaccine is in trials but I don't see it being approved and manufactured much less than distributed worldwide by September. Until there is a legitimate vaccine this pandemic won't end. Next year looks promising but this year not so much.
