I really have no idea.
Here's the keys:
1) if Vivek can convince Mullin to come in and complete the stupidity, Corbin is done as head coach, but could very well be asked to stay on as lead assistant/the real coach, while Mullin struts the sidelines during games.
2) if Mullin won't say yes, Corbin may have some lasting power just so long as he indulges every idiotic whim of the front office
3) if Mullin gsays no, but Corbin turns out to have some backbone/integrity, then apparently he too will be canned. This is no longer a professional setting. Yes men only need apply. We've got a power mad rodent and rich middle school coach to satisfy.
