Think as Dan said, it would be good for continuity and bedding in the new management team. He also has the benefit of not being tarnished by negativity as Robson now does. Be an interesting move for him if he does take it.
Would he be that big a loss?
Would he be any bigger loss than Barry Robson was to the coaching team?
He's done okay for an inexperienced manager. He still takes his share of the blame for whatever the players were being coached all season.
