This is the mock draft post Hornets Wizards trade. Also some "guarantees" have changed the order.

With the 21st pick in the 2012 NBA Draft the Boston Celtics Select:

Royce White

Position: SF
Height: 6-foot-8
Weight: 261 pounds
Age: 21
School: Iowa State
Analysis: According to sources, White pulled out of all his remaining workouts Thursday and has gone silent. He's not injured, and sources claim he's received a coveted first-round promise from a team. Promises are notoriously hard to pin down, but two sources are pointing in the direction of the Celtics. As long as coach Doc Rivers can buy into what White is (a ballhandling power forward) and figure out how to play him, he could be a steal at this point in the draft.

With the 22nd pick in the 2012 NBA Draft the Boston Celtics Select:

Andrew Nicholson

Position: PF
Height: 6-foot-10
Weight: 234 pounds
Age: 22
School: St. Bonaventure
Analysis: Nicholson is another draft sleeper who might really rise with workouts. He's a big stretch 4 who has drawn some comparisons to David West. He would be another welcome addition to the Celtics' summer makeover.

1 )  New Orleans - Anthony Davis

Jeff Taylor falls out of the first round. Also I can't see Eric Gordon and Austin Rivers playing off one another that well.
