My guess has been the only way we are likely to have NFL football is if they put all NFL players, families, coaches, refs, trainers, etc into a group quarantine a few weeks before the season starts and everyone has to stay quarantined until the season is over. I don't know if that's possible, but for the amount of money at stake I'm surprised they didn't at least look into this.
If one player gets sick (which will happen) there's a fair chance a good percentage of that team gets sick. What happens then? If a center gets sick the entire offensive line and QB are out for a month? What happens when the first player gets hospitalized or worse?
IMO the NFL would have needed to take steps that they aren't going to take to have a normal season. I really hope I'm over thinking this because it would really suck to lose NFL football this year, especially since this is the first year since the 90s where I can say without being a homer that the Bills are the best team in the AFCE. Hopefully somehow the season just gets postponed/shortened and not cancelled entirely. But I'd be really surprised if we get a 16 week season on schedule.
