He could get a cart, Zuca makes some with just Zuca on the cart and Rovaic or what ever the name of the company makes one backpack cart both carts being ones that can have a backpack on them and have a seat. However I have a feeling that Jeremy Koling is on the high side for dropping out,
Thanks for the info.
I'm sure Koling is well aware of the existence of carts. A cart doesn't really do a whole lot of good if he's dealing with sciatica. Using one might help prevent physical actions that could trigger or introduce the problem (like bending to pick up a bag over and over again), but once you're in pain, your throwing is going to be affected no matter what you do.
