I think Mcnamara would be good choice, he isn't a perfect coach but who is, I wouldn't judge him too much on his Bradford days, as he will have improved and learnt a lot since then, working for one of the best club sides in the world and under one of the worlds best coaches. He should come with some very good contacts in the game from here and overseas.
Well known to Peacock and Hugde also, I reckon he is your man.
I am surprised he would leave a great job like that though, for a risky one, unless he wants to move back for family reasons.
