I did look.....
Phoenix Coyotes yearly attendance at hockeydb.com
Attendance numbers in Glendale were 1-2,000 per game higher the first five years, than the last three years at AWA and for the past four years at GRA have been on par with those last three at AWA in spite of the team's performance.
Sure the arena would be in Scottsdale..... but would Scottsdale have shoveled out the $50 million over two years to the NHL plus agree to all the other subsidy support to keep the team there like Glendale did??? Ellman was playing with borrowed money he didn't have. The recession exposed this.
Scottsdale's city council was skeptical of Ellman and how much financial stability he had backing the Los Arcos project and they were proven to be right.
And if Glendale had not stepped up (to the tune of about $400 million when you add everything they've put into it) this franchise would have been in Portland the past 18 years. Consider THAT a gift.
