Great article Shawn.
To add to point #2 it is not only a force impact that is to blame. The 'old theory' of a contre coup (ie-the brain smashing off the skull) has been put to one side for now. Most of the research seems to be pointing towards torsional force of the upper cervical spine, and as such the brainstem. The torsional force is thought to cause microtears in the brainstem and is the likely cause of the visual, balance and other sensory issues.
Crosby is an interesting case. I actually know one of the guys who got him back from his last major concussion. A lot of what they did was to stabilize/normalize the upper neck and then re-trained his learned movements in a way that help lay down 'new tracks' in the cerebellum. An example he gave was as follows:
Sidney Crosby pre concussion could stand in the high slot and pick corners at will if you gave him a bag of pucks and called out where you wanted them to go. Post concussion having him do the same thing would do very little to get him back on track. As such we had to challenge him in a way his body did not know already. As such we had him stand on a bosu ball on one leg and fire pucks. This brought in balance in a different way while doing an action he was quite comfortable with. This helped to train his brain to revitalize a pathway.
I'm not saying they have it all figured out... but there sure is some interesting things coming down the pipeline. Clarke MacArthur is another interesting case as well
