"It's slightly counterintuitive, particularly since the Timberwolves are a young, rebuilding team and have already dealt their 2012 first-rounder. The pick they have now is the lottery-protected pick acquired from the Utah Jazz. With no shot at a top pick, Minnesota knows it isn't about to acquire a franchise cornerstone. The question then becomes, how much solid young talent is too much solid young talent?
Rookies represent great potential and great value to franchises, but only if they have the time to learn. Game time, mistakes and failure all provide great learning and development opportunities for a young player. When a rookie does not play much that first season, the chances that he'll become a good player diminish significantly.
Minnesota is poised to become a relevant playoff team soon and doesn't have available minutes to properly develop all its young players. Instead of adding another, it should get good value for the pick by trading it and addressing a need.
Certainly the roster might change a great deal by June, and if it does, perhaps a draft pick makes more sense. If not, it would not be surprising to see Minnesota target a player on another team's roster rather than one in the draft."
