If Jackson has had enough, in an odd way it's even more difficult for him that the fans have not turned against him. If they had, he could resign with their blessing (so to speak). Managing a struggling 3rd tier Club with an eccentric owner and confusion in the management structure is obviously hugely stressful. Added to which JJ lacks the experience and confidence to make bold changes. It seems he is out of his depth. Big changes needed in the summer (again). But we never seem to get them.
