The amount of butt hurt people following Hudson's career and dancing on his grave speaks loudly to how he made people feel. It seems he was very triggering, frequently turning fans into crazy ex-girlfriends.
Personally I've never understood it myself, he never bothered me, just struck me as an ambitious guy trying to be successful. It seems he isn't up to it, and won't be successful, but that doesn't make me hate him and want to disparage him at every turn.
Looks like he's just another guy out there who thinks he's better at his job than he really is, like so many other football managers.
