Using those arguments ignores the deeper issues, some of which we may not learn about for years to come.
See, there were similar arguments about Atlanta, and why no one wanted to buy and keep that team here. People claiming (and some, who apparently don't read the news, still claim) that hockey "doesn't work" in Atlanta. But, as some folks have learned, it just wasn't that simple here. What makes anyone think similar jumps to conclusions are that simple in Phoenix?
The NHL, the Coyotes, and local politicians talking up the greater Phoenix area and arena is no surprise. I would say they were all doing their jobs at the time. They're not the ones you should be citing, as history shows (and in the case of politicians, the history of glossing over facts to paint a pretty picture is quite extensive, dontcha think?)
