Take a peak at various 2012 NBA mock drafts, and you will notice how loaded it is going to be with freshmen and sophomores. These youngsters are going to be the center of attention leaving the juniors and seniors on the outside looking in.
If you ask me right now, I would tell you that only three juniors merit an early first-round pick.
UNC PF John Henson
Kansas PF Thomas Robinson
Mississippi State PF Arnett Moultrie
Besides the three individuals listed above, I believe no other junior warrants a Top 20 pick until you hit the later selections of the first round.
Many times if a junior isn't guaranteed a first-round selection by a team, they will make the decision to go back for their season year.
These are the five juniors who may be able to sneak into the first round of the 2012 NBA draft.
