Most teams play safe hockey when they have a lead in the 3rd period. A lot tougher to go through 4 or 5 players instead of 2 or 3.
3rd period they just had a lapse in their defensive structure for a stretch. Cost them a 2-0 lead. I expect that to get better.
Really doubt it is conditioning, but it’s certainly possible.
I'm sticking with gassed until proven otherwise. Hastings asks allot of his players.....
