Leeds probably wouldn't deal with Wigan but if Hardaker did become available there aren't many clubs in a better position then Wigan to move for him on a financial and reputation front.
By all accounts we've had the best part of a million quid come through the door in transfer fees with only reasonable money going out for Bateman and Clubb. The club has also said it has room to move on the salary cap front (although that was before Bateman) so you never know.
I would be stunned if a move for Hardaker ever came off but stranger things have happened.
