A division that's involved in the business end of championship every year.
O Regan had a poor reputation ever before he instigated this mess (with plenty of encouragement from Sars). That reputation didn't come from my buddies in the Hill who were often quick to defend him. People who have dealt with him in the Mon, with Imokilly and with Cork don't seem to have much time for him. You needn't do much digging to hear the stories.
Not that O Regan cares but I, and most people in the GAA would have zero respect for a guy that leaves his club for no apparent reason to move to a neighbouring club.
