No one knows when the season might resume, what it will look like when it does and whether an endpoint of 17 games and finals will be reached.

No one knows who will be involved at clubs for the rest of the season and beyond.

No one knows which players will return in good shape or what rules they will be asked to play under.

No one knows whether three grand finals will be played or where matches might take place in the home and away season.

Not even Collingwood coach Nathan Buckley, who makes it his business to know as much as he can about football, knows what lies ahead, and until he does, he is not going to buy into the ideas the AFL and club football managers raised this week in a brainstorming session, looking at what might happen when football returns.
