If we are buying a 2nd rounder for the purpose of getting a PG, I would wants us to pick either Lorenzo Brown (if he does not fall from the 1st) or Nate Wolters. Taller PGs who can shoot and pass.
Though I have reservations regarding picking another PG among the current draft candidates when we can utilize a 6'6" back up PG in TWill. If his current legal problems complicates the team's situation then maybe drafting a back up PG is a good one.
