There are seasons wherein it seems nothing happens, and then there are days where it feels like entire seasons happen. The Milwaukee Bucks just underwent one of those turbulent weeks that seem to turn everything upside down. They began the week in Detroit under a rookie head coach with, on the surface, a stellar win-loss record, and they now end it with Doc Rivers stepping into the void. For any number of reasons, GM Jon Horst felt that the project of this season may have been heading for a fall regardless of the standings. Those underlying issues do not completely disappear with the ejection of Adrian Griffin, but faced with limited options to effect radical change, Horst decided to pull one of the few levers he has concrete control on.
