When it comes to the bigger leagues, the broadcasters will eventually push for the games to go on behind closed door. Else there will most likely be a clause in their contracts which allows them to withhold money to the leagues’ since no product to broadcast.
Once that happens, we will probably follow suit and finish the league behind closed doors with skeleton crews for media coverage etc.
I’m personally all for scrapping cup competitions next season since the euro’s will get pushed back a year and have to be crammed into the schedule with things like Wimbledon, golf, cricket, remaining 6 nations games, Olympics and whatever else is affected.
