True. But he is going to land on his fronts first, which will take most of the impact; then he will include his back leg, which receives less of the impact.It's important I think to remember what he is dealing with and that it is a back leg where his jumping off/up/down abilities are harder because now the other leg and haunch have to do so much more where it wouldn't be as big of a deal as a front leg - weight distribution and all that.
