My preference would have been to trade Semih and Luke to Cleveland for Parker, a deal the Cavs were reportedly interested in. We still could have had two buyout slots for, say, Murphy and Powe.
That said, I think Danny thought Jeff Green was a lot more dynamic than anybody else available.
Green being a player is the only reason the trade makes any sense...but given the amount of time left in the season and Green never playing off the bench, I simply see no reason for this trade.
a bench with Nate, Dwest, Butler, Baby, Murphy, Shaq, JO, etc...has energy, scoring, depth, defense, size, 3pt shooting...on and on...
there's nothing lacking there, PLUS you keep your starting unit together....
