I do believe the theory of force absorption and force production is solid. The means to achieve it may be questionable.
I think the risk:benefit ratio is too high for majority of exercises. Do we really need to jump off a 4 ft box and land in lunge stance??
I feel variants can be used. I have used some picked up from Carolinaadi (if he still is around here). They are on a much less risky scale.
My experience is most athletes, especially higher level ones, can produce incredible amounts of force, but have major difficulty absorbing what they can produce.
