You have no idea what you're talking about. Parayko was fine, Scandella didn't need to try and take on a guy who already have two on him, and who wasn't even on Scandella's side. There was absolutely no reason for Scandella to come over.
Scandella was being aggressive it was passed to Colts side and he started being aggressive and challenging puck carrier. Both end up out of position and no forward covering for either when they are both being aggressive in the neutral zone.
Colt should of realized Scandella was out of position and stayed back instead stepping up,
Why we are trying to hold the area between the blue line and red line is another thing that makes no sense. You either hold the redline or the blue. Not no mans land in between makes no sense.
