THE NO. 1 ATTRIBUTE possessed by both players is poise. You have to pinch yourself to realize McAvoy just turned 20 and Provorov just turned 21. They match up against the opposition’s top players. They’re point men on the power play. They play in late-game situations. Both are used regularly in 3-on-3 overtime. In all of these situations, McAvoy and Provorov conduct themselves like seasoned veterans. They do not get flustered or chase the puck in the defensive zone. Longtime coach Dave King often told me the most important sign of poise in a young defenseman was the ability to find an open man in the middle of the ice when under pressure in the defensive zone. Most D-men either bang the puck off the glass, try to stickhandle or “freeze” while standing still. McAvoy and Provorov consistently make crisp passes to open teammates. These passes have to be accurate, because a turnover at that location results in a direct shot on goal. With McAvoy and Provorov, their accuracy is consistent.
