Demarcus Cousins vs. George Karl
George Karl will go down as one of the most successful head coaches in NBA history, yet he always had a way of getting his players to hate him, and burning his bridges at every stop he made during his NBA career. Karl’s clashes with former Sacramento Kings big man Demarcus Cousins were highly publicized, given the latter’s short temper as well. Karl repeatedly tried to trade Cousins, and when news of those trade attempts became public, it only served to sour the relationship between both individuals. After Karl was fired in early 2015, he had little problem airing out all his dirty laundry from Sacramento, calling the organization “dysfunctional” and essentially saying the team pandered to Cousins’ petulant behavior.
