This could be a clue to what this NFL season will look like. 

NFL teams HATE not making as much money as possible so the fact that the Bears are offering season ticket holder full refunds on the 2020 season and they won't lose them for 2021 pretty much says all you need to know about going to NFL games this year.

It's probably not going to happen.

The NFL is a little different animal from the other leagues. The teams and staff are much bigger so playing in a bubble like the NHL and NBA or trying to socially distance players and staff like baseball just won't work for the NFL.

Honestly, at this point it seems optimistic that NFL games will even be played this year, not unlikely, but definitely optimistic. But the thought of fans at games, at least anything more than 25% capacity seems VERY unlikely.
