While popularity and fan hatred fluctuate depending on geographic rivalries, historical success, and on-ice animosities, the Boston Bruins and the Toronto Maple Leafs frequently find themselves near the top of lists tracking the most disliked franchises across the broader National Hockey League community. The Bruins have historically embraced a physical, edgy, and abrasive style of play that draws the ire of opposing fan bases, while the massive media spotlight and passionate fan base surrounding the Maple Leafs often elicit strong antipathy from rival Canadian and American markets alike. Additionally, teams that experience prolonged periods of dominance, such as the Tampa Bay Lightning or Vegas Golden Knights, naturally attract widespread opposition from neutral observers.
