This is why I always say that being Burns' partner ruined him, he took too many bad lessons from the experience instead of continuing to use what were his strengths at the time. Got his wires all crossed up.
The way I remember it--which may or may not be true--is that he went from a good, solid defender who played a simple game, to one in his second year with Burns who was forced to suddenly become an improvisational defender.
That's why, even last year, he was capable of being a good penalty killer--he could operate well within that kind of structured defending. But with Burns he was put in a position where he had to scramble, he had to cover, he had to do too many things outside of his wheelhouse, and since then it feels like, with the type of guy he is, he's felt like he's needed to do too much because the team around him has struggled so much. And that DEFINITELY isn't his game.
We'll see how he does with Addison. Not a great defender but less free-wheeling than Burns. But maybe his puck-moving ability can help Ferraro in a sense because he won't feel like he needs to do as much in that regard, and maybe it could just help with zone exits. I do worry, though, that Ferraro truly won't recover his game until in a different system with a better all-around team where he can get back to just playing his simple game and he can feel fine about that.
