While reading this article on NHL.com I noticed that they mentioned several times that Jori Lehtera recorded a natural hat trick.
I assume they say natural hat trick to contrast it to another type of hat trick, but I don't know of any other types of hat tricks.
I have only ever heard them say natural hat trick when talking about hockey so I assume it is specific to hockey.
What other types of hat tricks are there in hockey, and are they that different that a distinction is required?
