Reese McGuire was taken with the 14th overall pick in the 2013 draft.
The evaluation of a draft can change over time. You first evaluate a draft at its completion, or after all of the players have signed. That evaluation is based entirely off potential, since obviously you don't have any results to go off of. As time passes, you start adding results. Potential still plays a role in the early years, but the further away from the draft you get, the less it becomes about potential and the more it becomes about results.
The 2008 draft is looking like a good one for the Pirates. That draft is pretty much all results, led by Pedro Alvarez, Jordy Mercer, and Justin Wilson. Plus there's Robbie Grossman, who was the biggest trade piece to get Wandy Rodriguez. Alvarez and Mercer are currently the left side of the infield, while Wilson is looking like a dominant reliever (and I believe he could still be a good starter if they stretch him out in the future).
