Personally I would prefer to see Kerr in to replace SOJ, rather than Jones/Jaksch. It would be a great opportunity to give him a run in the seniors and see how he goes in the lead-up fwd role - he looks like a very handy kick for goal. Agree that Jones/Jaksch would be more likely to replace Casboult if needed. Anyway, SOS may yet play.
Reality always wins in the end.
