Doesn't always work. Neil Aspin had a good record with non- league clubs Harrogate, Halifax and Gateshead. Port Vale took a punt on him and they languish near the foot of League Two.
Of course and no one is saying it is a golden ticket to success but it feels like giving someone the chance to step up is a better idea then letting someone hop back on where they fell off last time. Also, much more chance of them accepting performance related clauses I would think
