Ducks got robbed, distinct kicking motion my ass.
Ask a soccer player if that was a kick...
His skate was moving toward the puck when contact was made, and there was no reason for that movement other than to kick the puck. if he just glided in and the puck deflected off his skate, it would have been a goal. Probably (you never know with kicked goal calls).
This call was consistent with the rule and consistent with past calls.
However, past calls have completely ignored the rule as it is written (they often weigh perceived intent more heavily than whether there was actually a kicking motion), so I have long said the NHL either needs to change the rule to say what they want it to say (or remove the subjectivity from it entirely).
I feel your pain though, having experienced last season with the Devils where they were trying to do what the Ducks are trying to do now.
