When we gave this award to Mark Warkentien last year, the Nuggets GM had just pulled off a magical trade for Chauncey Billups, ridding the team of the tumorous Allen Iverson and positioning it to make a run for the conference finals. Since then? He's orchestrated a Draft Day steal for Ty Lawson, acquired back-court depth in the form of Arron Afflalo, and kept the Nuggets in a position to repeat — or even exceed — last year's run. He is, Melo aside, the team's most valuable asset.
