The Lords of Discipline have been woefully inconsistent but they correctly nailed Washington Capitals forward Tom Wilson with a 20-game suspension without pay for his needless hit to the head of St. Louis forward Oskar Sundqvist in an exhibition. Sundqvist might have had his head down, but that’s not illegal and it’s not an invitation to be hit. Wilson got him in the head, and that is illegal. And why smash a guy in the head in an exhibition? The NHL Players’ Assn. filed an appeal on behalf of repeat-offender Wilson, but maybe Sundqvist — also an NHLPA member — should be allowed to weigh in, too.
