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

The virus outbreak will have an affect on next season... whether it’s delaying or stalling offseason workouts and training camps, or delaying the entire start of the season.

But, I believe it will be in the Saints favor that they have kept their core together and have not brought in new players at KEY positions moving into the 2020/2021 season. Emmanuel Sanders is a savvy vet and it will not take him much time to adapt to the Saints offense (look how quickly he picked it up in San Fran, and now he has DREW BREES).
The Saints will have an advantage. They have kept their entire OL in tact, and that’s HUGE.
In the NFCS, the Panthers and Bucs both have new QBs... and even though they’re vets, there will be a learning curve for the entire offense of both teams.
