If the question is: What about GRA (which it shouldn't be, because it's not part of the Coyotes future in any way any more)?...
Then....Before the BK the Coyotes had management rights, and yes, in general, the arena in Glendale was competitive with the one downtown. But, as Legend has said many times....that's not enough for this market, and the real problem was the recession, which killed the momentum of Westgate, and led to Ellman splitting the Westgate development off from the hockey team. (Moyes would have been much better off never to have touched the NHL.) So, Moyes, the owner, was losing money in spite of having arena management rights.
After the BK, the NHL didn't really manage the arena at all, because they convinced Glendale CC to finance the hockey losses (25M/yr for 2 years), and that cost the arena its momentum.
When the team was for sale, and people were looking at IA, Glendale put out an RFP for arena managers, and one of the companies (which has since merged with another one) proposed an agreement without hockey, which would ahve been much better for the city. And, which, in hindsight, might have saved the arena as a profitable entity. {Essentially, if the team had left the market at that point, not only would the city have been off by at least 20M dollars (10M for each of the first 2 years of IA) PLUS perhaps lots more millions in arena management since.} {Point 2 on this....there would be no competing arena proposed in Tempe because the NHL would already be gone.}
However, since the BK, and IA managing the place for 3 years, the arena lost all its booking momentum, and has suffered since.
I wish Glendale well. I think the NHL and IA took them for a ride, and while not everything they have done has been completely straightforward, to me they are more victim than villian. But I think they have a tough spot, and I believe their best bet is probably something like what they are doing, and moving to a model which gives them advantages in the case of some genres of entertainment, because it's clear that they lose if they are trying to compete on a level field.
