Because there are no TV timeouts like in regulation which is when the ice crew comes out. The first whistle after the 10 minute mark is the only time they come out during OT periods, except for major fixes.In the OT Blackhawks iced the puck with their 4th line who as already on the ice for a very long time. The refs call out the ice crew despite the Canucks having the offensive faceoff.
Any idea why the refs would do that?
