Just my 2 cents for what it's worth;
My team, like everyone else's will have issues at the resumption of play. But, like everyone else, I no longer have to contend with Origin and Byes. To my way of thinking, that makes the whole game a lot more straight forward, and takes away a lot of the strategy and complexities... especially in terms of playing for Overall points.
So to me, giving us 2 trades to start with and having that as the foundation to fix all of our teams... that will be the most strategic and complex thing we'll have to get around all season. After that (however many weeks it may take), simply speaking, it's all smooth sailing (until the Second Wave shuts the entire game down for 2020).
Obviously they'll have to adjust the amount of trades we're given for 2020 but apart from doing that, I tend to think the silent majority would be pretty understanding, going into round 3 with 2 trades. To differing degrees, we'll all be put out a bit but I think most people would take it on the chin and get on with it.
The issue is going to be, as in life, the vocal minority. And it'll be trying to appease these people that will create dramas, I suspect. Because if they don't appease these punters I guess the fear is that a lot of people just throw in the towel for Fantasy in 2020 and walk away, which is not what they'd want.
I feel like giving us ample opportunity to all fix our re-starting squads is what will keep most people playing Fantasy in 2020 and therefore I'd assume they'll go down some variation of that path.
