That first goal was pretty by Barzal. He used his gifts, was decisive, and powered that shot through w/ his core. Generate power through your core. Stick to the wrister (use the offseason to continue developing the shot, f*** IG pics.)
When I see MacK, he uses his gifts and attacks. Barzal used his gifts (edgework), and a semblance of a shot; he then attacked.
This team, as expected, are hanging in. They always do. Just a tier more of talent, this series would be at a different place; deja vu.
The Canes are going to bring their A game; use this momentum, match it, and take it. Two days rest should benefit Varly.
