Yes it does.

First of all, its extremely obvious following a sport like hockey. If the jaw/chin is caught by a shoulder/elbow, people are knocked cold. If someone is hit anywhere else in the head, 19/20 times there are no problems.

I played hockey until I was 21 y/o. I played in a men's league from when I was 16. Besides hurting my ears maybe, I never even felt pain from hits to the head anywhere but the jaw. And you have players falling on your head quite often in the game and what not (hitting the board head first with the top of your head when hit from behind etc), but then you where caught on the chin (and it didn't need to be particularly hard) and it was lights out and head ache for two weeks.

So there is definitely an enourmous diffrence betwee being hit in the jaw or like being hit to the side/back of the head. You have the helm protecting the rest of the head and it absorbs/spreads some of the impact, and;

Second of all, the explanation I've heard numerous times from doctors is basically that the jaw is pushed back into the brain somehow.

Just google:
When the jaw in impacted from a hit from any side or underneath there is a transfer of energy through the temporomandibular joint to the base of the skull.

In boxing the jaw is called the button ...
Impact to the Jaw: If there is not adequate cushioning of the jawbones, they can be pushed into the base of the skull and even the brain cavity. This dangerous blow can disrupt brain function and activity causing a concussion as well as other skull damage.

Forceful Blow to the Head: A concussion can take place when suffering a forceful blow to the head. When this happens, the head accelerates rapidly and is then suddenly stopped. Although head movement has halted, the brain, which is floating in cerebrospinal fluid (CSF), is shaken and hits the interior skull wall.
In short, if you are hit to other parts of the head, you need the head to litterary move very fast and violently, but if you are hit to the jaw you just need enough force to slam the jaw back against the brain and that jaw isn't that strong...

That is true for sure, but you especially see people with concusssion problems suffer from these milder types of concussions. I definitely think they contribute largely to the concussion problems in hockey. IE, the "three" major concussions a player have had in themselves might not have done all that much damage, but besides those three you probably have 3 000 impacts that impacted the brain with some type of energy level and the 3 + 3 000 results in the problems we hear about.
