Lalancette thrived in the second half of the QMJHL season. The skilled playmaker started to gain confidence and displayed good skating and puck skills. His puck skills outside of passing the puck leave a bit to be desired for a player of his archetype but he makes up for it by working hard on both sides of the ice. He is not known for his physical play, but even despite a smaller build when he does hit, he hits hard. He will need to continue to add strength over the coming years and work on his shot if he wants to ever make it to the NHL.
The young forward will begin his third season in the QMJHL with an entirely new team after an off-season trade to the Drummondville Voltigeurs.
