Maybe Youkilis does belong in that group. From Jackie McMullin:
Kevin Youkilis has always been a hot button. On occasion, his intensity and his honesty were his biggest assets, but not this season. The injured Youkilis showed up every day the way he wanted Ellsbury to, but he turned so sour and cynical that his carping and insistence on inserting himself into other people's affairs turned him into a detriment.
