10:41 AM ET 07.29 | Prospective Phoenix Coyotes buyer Greg Jamison is approximately $20 million short of the money he needs to buy the hockey team and keep them in Glendale. The Coyotes deal is on tenuous ice but could still happen, according to multiple sources familiar with the team's three-year ownership saga and uncertain future in the Phoenix market. Some of that new potential investment money could come in if the city of Glendale prevails Monday in court hearing regarding a sales tax ballot measure. Glendale disqualified a ballot measure earlier this month aimed at reversing a sales tax increase that helps pay for the city's $300 million arena deal that helps Jamison buy the Coyotes. The Coyotes are almost certain to play in Glendale next season even if the Jamison deal has not been finalized.
