The biggest issue with downtown is the Suns don't seem to be willing to partner with the Coyotes 50/50

Their lease runs for another 6 years before there's an opt out for a new building (they can kick-start the discussion in 2019). The Suns control the revenue streams from their current building. Not much of an incentive to end that contract early just to start sharing the revenues with the competition.
