The Montreal Canadiens defeated the New York Rangers 2-0 on Monday night, and Alex Galchenyuk scored a 2-0 dagger with 2:51 left in the 3rd period...With his foot. The NHL's "Situation Room" upheld the goal...

But the Rangers were not amused, especially given that J.T. Miller "scored" a similar game-tying goal against Philly which was waved off last Thursday:

I grew up playing soccer before I took up hockey as a teenager, and the fact that he both extends his leg and straightens his knee equal a kick in soccer. As far as I understood it, the point of the rule is to allow goals where a player simply turns his skate to allow the puck to deflect into the net off of his skate, but denies goals where the player extends his leg to propel the puck into the net.
