The Wizards will likely use their first-round selection (No. 3 overall) on either a small forward or a wing player.
If the Wizards go small forward at No. 3 (likely Michael Kidd-Gilchrist), then they need to nab a shooting guard with the 32nd pick, which is the second overall pick in the second round. If the Wizards go for a shooting guard at number three (likely Bradley Beal), then they need to take a small forward with the 32nd pick.
The 46th pick is in the middle of the second round. At that position, the Wizards can take a chance on a project player or a serviceable depth player. The second round in this year's draft is very heavy with senior big men. The Wizards lack depth at the center position and could benefit by adding an experienced big to spell Nene.
In an effort to purge the team of rotten contracts (Rashard Lewis and Andray Blatche), it is very plausible that Washington GM Ernie Grunfeld makes a trade or two, and the Wizards add another one or two draft picks.
John Wall is entering his third season, and if he is not surrounded by winning talent, he is not going to be excited about signing a contract extension. This draft will add another one or two starters that should be the building blocks for the Wizards future.
