They toughened up that rule after Crosby slashed off Methot's fingertip last season.
I like the rule for the hands/arms, anything above the belt, anything to the groin, and any two-handed lumberjack swings.
I DON'T like the rule if it's just smacks to the shin pads or pants - like Boll's last night - or if it's to the stick below the bottom hand. All of your life as a hockey player you are taught to get body position and if you can't get body position, GO TO WORK ON THE OTHER GUY'S STICK. Good stick work is good hockey. You should be able to aggressively attack another guy's stick.
