If you take a step back Dolan is the constant. He stepped only after he starphuched himself with Phil because of the star power he had.
Remember it was the persuasive Irving Azoff a friend of Dolan’s who got this marriage going and Dolan chased Phil around with money too big to say no to. Phil, for all his wizardry was proven to be a miserable executive.
Remember he hired Mills first then Phil.
Only since Phil was fired do we have a hierarchy in place that is “normal”.

excluding dolan:

constant change.
no patience.
