Now that my son has graduated from college, I can say this without jinxing him – he never had an injury!* No concussions, no knee injuries. Literally the only injury he had was a broken toe when he was in 5th or 6th grade.
Understand that the two doctors on the thread only see injured players, by definition. Which is not to say there isn’t a problem, but that their experience is skewed.
Besides conformation, perhaps one reason my son was uninjured is that I viewed his soccer playing as a marathon, not a sprint. So he took summers off from competitive soccer etc. Frankly this was more due to my belief that mental burnout was more of an issue than physical injury, although that was a factor in my thinking too.
*eta, I mean an injury with lasting consequences. Even then, the only more superficial injury I can think of was a knee laceration that needed 4 stitches.
