This is what I'd do if I'm the Wizards, this is the unrealistic version, make sure to check out the more realistic one

1: Trade Westbrook and 3 SRP to the Knicks for Knox and 1 FRP

2: Trade Knox, Bryant, Avdija, and Gill for Myles Turner

3: Let Hutchinson walk (team option)

4: Trade Davis Bertans and 1 or 2 SRP for Grayson Allen

5: Sign DeMar Derozan for a 3 year 80 million dollar contract

6: Sign Kyle Lowry to a 3 year 66 million dollar contract

7: Resign Raul Neto to a 2 year 5 million dollar contract

8: Resign Ish smith to a 2 year 10 million dollar contract

9: Sign Semi Odjela to a 1 year 2 million dollar contract

10: Sign Jevonte Green to a 1 year 1.5 million dollar contract

Right there, they have a team with a good chance of being a real threat in the playoffs. Having Lowry-Beal-DeRozan-Haciumara-Turner with having Smith-Neto-Allen-Gafford being a few good players off of the bench, they would be a real threat with there starting lineup, and there good enough bench.
