It was pretty much a foregone conclusion since the season ended, but it has been reportedly officially nonetheless:
Wiz signed 1st rd picks John Wall & Trevor Booker; also renounced the rights to FAs Mike Miller, Randy Foye & Josh Howard (no Bird rights)
Mike Miller has offers all over the place, most notably from the Miami Heat, and Josh Howard and Randy Foye will explore their options in free agency. Both are likely to receive pay cuts next season.
