"It's all about execution and hard work. We've got to do a better job of controlling (Nathan) MacKinnon and (Tyson) Barrie. For me, yesterday, I showed a bunch of clips to our coaches of Barrie jumping by us, creating 3-on-2's, 4-on-3's. They go, 'Oh, you showed me that one already.' I go, 'No. That's a different one.' There's too many examples of it, so we've got to clean that up. We're well aware of that."
