If you are dropped for poor performance, well, it means you have things to work on.
If you are dropped for team balance, it means you have things to work on (otherwise someone else would have been dropped for team balance).

I refuse to believe any player who is left out isn't given details as to WHY they have been left out and what they need to improve. And I further refuse to believe that that message wouldn't be consistent from the footy manager to the development coaches.

It's OK to be dropped - it really is. I am sure when he is ready to go he will be back in. I can't explain why he didn't play VFL in his first week out - who can apart from Bevo? - but I am sure he is working off a development plan...
