I like this trade a lot. I doubt Minnesota does it, but if you are Boston you have to.
Derrick is a young kid, he hasn't lived up to his draft position but has potential as a player and as a trade chip.
Shved is a great talent, he showed last year and in Europe. He's looking pretty bad this year, but he's playing less than 9 minutes per game. He still has potential and his contract is highly tradeable.
Dieng is a big on a cheap contract, he's tall and he could become a solid backup. A good asset to have.
Of course the Cs would be giving up the best two players in the trade, but getting 3 prospects and saving 3rd year money from Lee's contract is the right thing to do at this point. And the Celtics would cut 2M from the cap, too. Not bad.
