I don't think that is true.
Going by what he has said over the past couple of weeks I think you'll find the following is more correct:
1. Big changes to zones cause instability and there is no way to measure improvement/failure in their systems.
2. He wants to give the defence time to gel as they have only been playing as a unit for 4 games.
3. Incremental changes are his preferred choice to measure what will and wont work with this playing group.

To be honest it is the right way to go about it from a statistical and probability stand point.
Coupled with the fact we have 0 depth, he doesn't really have a choice.
Like some have already said, he inherited a relatively poor list and has made lemonade out of lemons, but there are still too many lemons.
And Austin and co, have not really set the world alight with bringing in mature depth or quality when our window was open.
Like I've said for 3+ years, we needed to add mature class to our midfield but instead, last year we put 2 drafts hope on an 18 year old kid.
This is beyond poor list management, if we traded in another older player like a Jack Macrae to settle the midfield and help the kids we wouldn't be discussing this right now.

His job is to be a parental figure, mate, best friend, etc to get players to believe a story, play together as a group and get the best out of them.
But going by his presser on Thursday, he won't be having too many mates for awhile unless they start performing.
However the risk is and as we know, Carlton players go to water when the going gets tough because they know we will sack the coach instead of them.
Time to change the narrative.

Had a chat with an ex player of ours recently, and he agreed with me, resoundingly.

The lack of accountability in selection highlights this, regardless of depth.

Maybe he's afraid of losing the players?

An effect of failure, so to speak, from his Brisbane coaching days.
