Minor point, he has had a habit of drifting into the corner unnecessarily after the puck carrier, but I noticed one time in particular, that stop himself and stayed and protected the net, a little but positive sign.
It's a change in strategy after the coaching change.
You could often find two defencemen below the goal line under Monty. Under Sacco, one always stays net front and a forward attacks with a defenceman.
It's not perfect yet. There will be an adjustment period.
For Zadorov in particular, he was already learning a new system, then 20 games later learning another new system all over again.
