Yes.
My understanding is, Sullivan is the coach who can do whatever he wants WITHIN CERTAIN PARAMETERS THAT THE MANAGEMENT HAS TOLD HIM THEY EXPECT. Insomuch that JR made certain expectations clear to MJ, they were reinforced as part of Sullivan being given the job.
On top of that, it includes instilling the sort of control over a team the coach should have (regarding accountability, play time, etc...), and it was thought that a 3-year deal would be best to give him that authority.
If the team just falls apart and misses the playoffs, don't expect JR and company to be like 'oh well, let's try again next year with the same setup!"
if I did this, people would just say I'm doing it for attention. There's literally no way for me to say anything that doesn't offend someone's sensibilities. The idea that I would just invent something that people don't like, simply to piss them off or something.
