Heiskanen was not a finalist for the Calder Trophy given to the rookie of the year last season, in part, because he tallied "just" 33 points (12 goals, 21 assists) in 82 games. But those who watch him on a regular basis say that his ability to see the game, anticipate plays, and keep his team in a good place is incredibly underrated.
The Stars have battled some of the best players in the league in recent weeks -- facing the likes of Nathan MacKinnon, Patrik Laine, Johnny Gaudreau and Elias Pettersson -- and Heiskanen usually has had the assignment of trying to shut them down. But maybe the most impressive feat was when assistant Rick Bowness tried to get Heiskanen out against Connor McDavid as much as he could when Dallas played on the road against the Oilers last week. McDavid finished with three assists, but they didn't come against Heiskanen. The sophomore blueliner had a goal, an assist, and seven shots on goal in the game while finishing plus-1 in a 5-4 overtime win.
"He went head-to-head (with McDavid) and we had him with 10 chances for and one against per our scoring chances," Montgomery said. "That's an elite game."
Heiskanen was on the ice for a goal against that looked like his fault early in the Oilers game, but Montgomery said further film study said it was a fluke.
"He was really good the entire game," Montgomery said. "He had the one goal where the puck went off a shoulder as he tried to get it out. I don't think that was a mental mistake. He was dynamite from start to finish that game."
