Although it is officially prohibited in the rules, at the professional level fights are sometimes used to affect morale of the teams, with aggressors hoping to demoralize the opposing players while exciting their own, as well as settling personal scores. Both players in an altercation receive five-minute major penalties for fighting. The player deemed to be the "instigator" of an NHL fight is penalized an additional two minutes for instigating, plus a ten-minute misconduct penalty. This so-called instigator rule is highly controversial in NHL hockey: many coaches, sportswriters, players and fans feel it prevents players from effectively policing the objectionable behavior of their peers, which is often cleverly hidden from referees. They point to less extreme on-ice violence during the era before the rule was introduced. Toronto Maple Leafs owner Conn Smythe famously observed that "If you can't beat 'em in the alley you can't beat 'em on the ice."
