My god, the officiating is just plain horrible.
Let's review: A knocks B off his skates, who slides at high speed into A's goalie. Result: B gets a goaltender interference penalty.
Tepid stick-work: a slashing penalty. And by tepid, I mean tepid. The only time this would get called in the regular season would be if it was a Toronto player, and the Toronto team had been bitching about the bad officiating non-stop for the previous week.
Knocking someone off the puck, from behind, onto his face: no call because ITS PLAYOFF HOCKEY, DUDE!
