Is there somewhere that a list is posted, and without violating HIPPA, does it say what the issue is for the player? Upon further review, and looking at the question "is it S&C issues", I think you can pretty easily break down the categories as to what may or may not be caused by training (or lack thereof). We have two concussion protocols and one broken leg, I'd say those fall into the "non-S&C" column. I'd add to that any illness, Injury received outside the confines of the program (thinking paintball to the eye here), deep muscle bruising, prior injury aggravation, and position related (meaning over time if you play a certain position you are going to have this injury no matter what, and no, I can't give any examples).
On the S&C that would leave pulls (hamstring, groin) ligament, tendon or muscle tears, turf toe (is that positional?), strains, and separations. I'd further divide that group into contact and non-contact (no amount of conditioning will save an ACL when a foot gets planted and a 300 pound linemen pushes the body in the wrong direction). Conversely, if a guy is running wide open and full out and suddenly falls to the ground grabbing his hamstring, there might be an issue with S&C.
