Todd, Sometimes you can really come a crossed as a real jerk in your responses.
Your asking for statistics that barely exist and when you do find them they are from years ago and studies that were not fully completed or for that matter, included box Lacrosse.
For you to insinuate that Spine and Neck injuries rarely happen in the sport of Box Lacrosse is ludicrous. Makes me believe you haven't been around the sport for that long, and I am sure you have so your response baffles me.
Go ask your local Chiropractor if he/she has seen a spike in Lacrosse players visiting there offices in the last 5 years and I will be shocked if the answer you receive is No.
