I forget who it was, but he was talking on Gottlieb's show today. He says the achilles' problem is because of the drop back. The hard forward, quick stop or side, and then drop back and shoot. It is very common today, but the training hasn't adapted so they don't actually train for that like they do the slides and other moves. They do it in practice some, but not the training with weights and what not. And because they guys are so big, strong, and fast that that sudden move weakens the achilles. Couple that with the lack of training, and that is why there is an uptick in that injury. He also said you couldn't really count Haliburton's or Lillard's because they were both playing with lower leg injuries and that causes favoritism (which is also what happened to Durant), but most of the others he attributed to a lack of training. I have no idea if that is accurate, but at least in theory makes sense to me.
