It's not about 'growing balls', as many have said.
The ARU over leveraged themselves financially, and so they CHOSE to cut a side. When a company is so close to insolvency that it goes through solvency tests, you either have to come up with new revenue streams (any ideas?) or cut expenses. If you do not do this you WILL become insolvent. This would undoubtedly be a worse outcome for Australian rugby than either the Force or Rebels organisation ceasing to exist.
It's not incorrect to say the ARU have shown incompetency to get to this point, that the situation was badly handled, and that it continues to be badly handled.
But, in a vacuum the decision to cut a side makes sense.
I feel disgusting saying that, but it's just plain right.
