As McAvoy, now in his second full season, adjusts to the rigors of the National Hockey League and finds his bearings following a number of unusual injuries over his first two campaigns, Bruins coach Bruce Cassidy is practicing patience.
While McAvoy's high-end skills make him an easy choice to play alongside longtime stalwart Zdeno Chara to form Boston's No. 1 defensive duo, Cassidy knows that there will be plenty of learning curves for the 21-year-old.
"[He plays] against anybody, plays on the power play, plays on the penalty kill and moves the puck, so a little more modern-day type of player, does a little bit of everything," said Cassidy. "If you look at the Drew Doughtys, the [Roman] Josis, [P.K.] Subbans, whoever you're going to put in those categories - we hope that he's in that category at some point.
"But again, we want to temper that so that when Charlie has the usual 20-year-old hiccups we don't get down on him."
Hiccups were hard to come by during the Bruins' two OT victories over the weekend, with McAvoy appearing as comfortable in his all-around game as he has all season. The Long Beach, New York, native contributed three points - including his first goal since Oct. 13 - across the two victories, during which he also landed a combined six shots on goal.
The offensive engagement could be in direct relation to McAvoy's willingness to shoot the puck. In the 12 games since his return, he has landed 24 shots on goal, after pumping just 15 shots in his first 15 games of the season.
"Maybe he's starting to feel like now he's into form, right?" said Cassidy. "It's not that easy in this league to miss five weeks or four weeks or whatever the case was each time and then all of a sudden get back and revved up to full speed. And the expectations are high for Charlie. He's had a good start here.
"Part of that we try to temper with him without talking him down and not reaching his potential, but he has to understand it's a tough league and play the game in front of him. And I think he's starting to now play that way, and then when the opportunities are there, he looks like to me that he's taking advantage of the situation.
"He's not forcing anything, so that's a sign that a guy's in a zone when you have the puck a lot. You're making plays, yet you're not forcing stuff and seem to be making a lot of the right decisions. He's in a groove right now."
