This is a borderline insane thought, but the more I ponder it, the more I would likely do it. It involves trading Rondo and taking back Rashard Lewis's terrible contract. Here we go
Wizards get Rondo, Allen, Oneal, and a #1 Pick
C's get Wall, Mghee, Lewis, and Nick Young
Currently reports say Wiz are accepting offers for Mcghee the only untouchable is Wall. My thought is if the C's give them salary relief by taking back Lewis's contract and Rondo, the Wiz may give up Wall. Put Wall on the C's and he can make the fans forget Rondo. Mcghee is a knuckle head, but he is more talented than Deandre Jordan. With Doc and KG, he could develop into a star. He would definitely solve all the teams problems at center. Nick Young is another knuckle head, but he is very talented. Lewis..., well he has a terrible contract, but he is relatively young. He could help the team this year. C's would only be strapped with his contract for 1 year. It might be a reasonable price to pay for a chance at Wall and Mcghee.
