During his commentary on the Golden Knights' Game 5 against the Dallas Stars, Cassidy made a comparison to the Arizona Coyotes that implied they were a lesser team in the league and unable to win with 24 giveaways. This comment was unprofessional and bordered on being antagonistic, which is not Cassidy's usual style of dialogue.
After receiving backlash, Cassidy apologized for his disrespectful remarks, which he called "Disrespectful" and acknowledged that it was unfair to bring the Coyotes into the conversation.
Despite Cassidy's comments, it should be noted that the Golden Knights did lose to the Coyotes 4-1 in Mullett Arena this year, but only had two giveaways.
