I can add a bit more to this, JH lives about a mile from me in a delightful little village between Bradford and Leeds. He can be on the motorway in under 10 mins. The training ground is about 1hr 10 on a good run, so not too bad a commute.
Sheffield would be about 30-35 mins and Rotherham largely the same.
However, Bradford City are going to be throwing some money around this year and have some very lofty ambitions; whilst a move to League 2 would seem mental, they will certainly be looking at players like JH im sure.
