Interesting. Alex & Tommi recently have been blogging on this. I commented on their work on my page.
The interconnectivity makes sense. One thing I've learned in my own training: It's sometimes hard to figure out the injury of you only look at the site of the crash. Sometimes you need to examine the big picture.
Alex and Tommi are busy doing some fantastic work on testing and experimenting performance outcomes based on Gary Gray's 5-Zone concepts. Some of the movement analysis videos they showed me just last week are showing some interesting observations in power and agility. Very exciting stuff.
Those two guys are definitely world class professionals in human performance!
