Was watching the Isles stream and they mentioned how long he and others were out early after they pulled Gilles and towards the end were off because of it. Definitely made it out to be him and others being gassed. Look though I agree you need to figure out how to have him out there.
But imo they (team from the coach down to every player on the ice) botched the last 2:21 with the complete lack of urgency. Not just the passing from point to point but dicking around in their own end and just wasting so much of the final 2 mins overall before "going" with what 30 seconds left? Just getting the puck into the zone seemed to take forever, literally.
