This is the one thing that I think Roy screwed up on royally. He compounded the teams's problems by constantly shuffling the lines. A couple or few times would have been understandable, but there's been almost no consistency at all to develop chemistry, after some fairly big positional and roster changes in the top 6.
The team can't score, and they can't read off each other in the defensive zone, but he thinks it's smart to keep moving the pieces around.
He talks a lot about them not panicking, but it feels like he's ben panicking since the start of training camp when he left the lines he talked about in the summer together for 1 preseason games, and continually shuffled things up, never really kept the same units together for more than a couple games all year.
It usually isn't even a couple games that they're together either. It's like one half of one game and one or two periods of the next game.
