I think that supercompensation is not as strong an effect in amateurs and that this is the #1 driver of injury.

I've long suspected there is a range of exertion that is net negative with regard to injury risk. No exercise at all means no exercise related risk. However, I strongly disagree that an extreme amount of exercise is the riskiest. I think the most dangerous level of exertion sits right in the middle somewhere. That special zone where you are grinding down your bones a bit but your hormones and other compensation mechanisms don't react accordingly because you aren't going quite hard enough.
