OK, so I'm thousands of kms away, though I've been watching the Coyotes with interest for over a decade, but if others have better information they can and should correct me.
The City of Phoenix owns the Footprint Center (formerly Talking Stick, formerly US Airways, etc), although the building is managed by the Suns. The City of Glendale owns Gila River Arena, the now-former home of the Coyotes. A new Tempe arena would compete directly with both of those facilities. It would potentially give leverage to the Suns whenever their arena deal runs up (as in 'give us a better deal or we're moving to Tempe').
So that would be Phoenix's motivation to block a Tempe arena. Plus you'll always have certain elements come out against 'taxpayers subsidizing pro-sports".
Well, living here, there ain't no way GLENDALE's former NHL arena was really competing with the Suns Arena or the Coyotes Arena. Not when I have to take a day off from work to attend an event in Glendale and have lightrail access to the Suns/DBacks where I can pay $4 for a train instead of find parking, and sip concealed booze on the way there and sober up on the way back.
Tempe Arena vs Suns Arena is a legit concern, I suppose. But hardly. This time of year is when they'd be competing for acts; and there's only 21 events booked in the Suns Arena that aren't NBA/WNBA/Arena games through from now until the end of the year.
There's 6 million people in the market. Any touring event is either not having a problem doing 18,000 a night in Downtown and 1-2 nights later Tempe or vice-versa, OR is big enough to do 40,000 one night in Chase Field.
It's the medium-sized "one-off" events that they'll fight for. And again, it's a market of 6 million people, with 25 venues over 5000. They probably have plenty of THINGS they could host and don't. What are they afraid of losing, the IceCapades?
Meruelo has had issues paying his bills on multiple occasions. There is plenty of reason to believe he has shaky finances.
Is this based on anything other than the Coyotes' dispute with their former arena in Glendale?
