From what I have heard, this was Skiles' decision, not Milwaukee's. Skiles told Bucks' brass last month that he would not seeking an extension on his expiring contract. I guess he decided he'd rather not be a lame duck, and just quit now.
Seems like something he'd do. Has always struck me as a bit of a little tyrant. Might be a good Xs-and-Os coach, but everything I have heard about him says his interpersonal skills are lacking.
If anything, I expect the Bucks to play freer and easier, and still contend for a low playoff berth. The chains are off. Fear the Deer?
