8:31pm: Adrian Wojnarowski of Yahoo! Sports adds Celtics assistant GM Ryan McDonough to the list of finalists. McDonough interviewed Tuesday with Babby and owner Robert Sarver, and Weltman will interview Thursday. The Suns want to make a hire quickly so they can decide on a coach and prepare for the draft. Babby made a push to hire Weltman in 2010, when Sarver favored Lance Blanks instead.
5:03pm: Spurs assistant GM Scott Layden and Bucks assistant GM Jeff Weltman are rumored as the finalists for the vacant GM position in Phoenix, according to Gery Woelfel of the Racine Journal Times (Twitter link). Milwaukee gave Weltman approval over the weekend to interview for the Suns job, while this is the first we've heard of Layden in connection with the opening. Chris Broussard of ESPN.com reported Weltman was the frontrunner for the gig last week.
Layden has only been on the job in San Antonio for eight months. He previously held GM jobs with the Knicks and Jazz. Weltman hasn't run a team's front office before, but he's been with Bucks GM John Hammond ever since Hammond came aboard in 2008, and prior to that, Weltman and Hammond worked together with the Pistons.
Whoever gets the Suns job will decide who will coach the team next season. Interim Lindsey Hunter is still Phoenix's head coach, but he appears on shaky footing, and is interviewing with the Pistons for their head coaching vacancy. Suns president of basketball operations Lon Babby is promising a "summer of analytics" for the team, so presumably the next GM will be a devotee of advanced metrics.
