I haven't seen too many golfers jumping up as they swing their clubs, or even lifting one foot to place
all of their weight on one foot, or for that matter quickly falling back and setting, where that back foot might as well be carrying all or most of the weight......plus the inertia imposed by the fall back.
There admittedly may be some stress on Schaubs back foot when he golfs. But, assure it's a spit in the ocean compared to the expected stresses he will experience on the football field........that's not even taking into account the unexpected elephant that happens to increase some of those stresses.
