Think it over...most of us would rather skip the NBA regular season and get to the playoffs...even a little late is OK.
Every year the number of people who actually care about baseball is reduced so they can skip the season if they like.
The NFL can cut back pre-season and start the games in late Sept and by even the most dire estimates, they should be clear of the virus issues by then. You can use the China timeline and easily fit the NFL start in that window.
Using China's timeline is not wise. They aren't telling the truth! People, don't be naive. Sports is the least of anyone's concerns. Life as we know has changed and there will be changes to normal living on the other side of Covid-19. You may not see sports for the rest of this year. And that's not an overreaction in my opinion.
