I'm confused. If this were about the complexity of the Pens system all along, what was the purpose of this:
A team "adjusting/executing back" really has nothing to do with Maatta's current problems, in that case. It's Maatta making mistakes that he wasn't making before (and others aren't making now) in an involved system where defensemen need to be sharp. That's on Maatta, not anyone else.
See what I just wrote above. I hope that clarifies. Otherwise, I've got no idea what further to do.
Let me ask you this: If you do something in a hurry, then what's the upside? You finish first. What's the downside? You're more likely to make a mistake.
That's all the Pens quick breakouts and having defensemen exit the zone quickly is about. If it works, they're pressing an advantage (or mitigating a talent disadvantage due to injuries). But, the downside is that the likelihood of a mistake increases.
I see two factors at play . . .
1. Maatta is spent, which makes bad decisions more likely.
2. He's rushing to throw the puck up ice, which is what the system calls for, and is seeing the downside of the increased likelihood of mistakes, just as he was seeing the upside of the system vis-a-vis his offensive game, four weeks ago.
Two lesser factors:
1. There's a lot of turning and moving the puck in one motion, and what he's expecting to see in terms of where his players and the other team's players are isn't what is happening.
2. Little confidence.
What factor accounts for what in terms of Maatta hitting a wall? I don't know. What was it for Letang earlier this year? Nisky when he had a few off weeks? Orpik always? Even Martin at times? Everyone is different. But, you've still got a high risk/high reward system that is a factor, admittedly to different degrees, in both the good and the bad, with Maatta and anyone else.
