It's well known that Cole Caufield brings a sense of joy and fun to the Montreal Canadiens' locker room.
Martin St-Louis has noted that during Caufield's serious injury that ended his last season, it wasn't just his goals that the team missed, but also the positive atmosphere he contributed to the team environment with his presence.
He is a lively and beloved teammate, making him a valuable player for the Canadiens, not just for his on-ice performance but also for his off-ice influence.
To give you an idea of the kind of atmosphere Caufield brings to the team, a viral scene shared by the Canadiens perfectly illustrates this.
