The video review and coach's challenges have been quite constroversial over the last few seasons. It appears that the League is ready to take measures to resolve those issues.
From Darren Dreger:
"Rule tweaks in the NHL. Puck over glass will eventually be a Coaches Challenge to remove penalty as will «Friendly Fire» high stick penalties. Other small changes also expected. These are recommendations that go to the competition committee and then to board for final approval."
