It’s because of the amount of repetitions our players have in it in such great quantities, creating a “last straw” situation on primarily our guys. Imagine a burlap bag and it’s fibers, the fibers start to fray and break weakening the ligament fibers one by one til the overall tensile strength is lost to allow the final straw tearing of it wholesale with (ANOTHER) non contact injury to the knee which this one was another example of him crumbling down like he did from a simple upper body block.
As someone who played on turf (gonna use this response Rick for an overall message in this thread), grass all types of surfaces, then taught orthopedics for 30 years with special attention to the various mechanisms of injury associated with knee injuries and the specifics knee injury types themselves(acl vs. mcl, meniscus all of the above etc - or all the above), then spending time on the turf assessing it with my own various movements on it, I can say with certainty it’s the turf.
This is the only team I follow closely so as someone suggested above a serious study need be done and as an edit I don’t think our turf is unique so I’m sure it’s happening all across the nation in greater numbers as shown to be true in another thread that was posted showing research on this:
As I suggested elsewhere a return to the old type turf but with better padding beneath is the answer so it doesn’t feel like concrete. As it is this new turf is too spongy transmitting too much energy force into these kids knees.
