In his first season with the Blackhawks, the 25-year-old Panarin won the Calder Trophy as the league’s best rookie after recording 77 points (30 goals, 47 assists) in 80 games. He’s followed that up with another sensational start to the this season, with a team-high 37 points in 37 games. His 15 goals are tied for 10th in the NHL and his 37 points are tied for fifth-best.
