I selected "No, keep Green and forget Melo. He's not a franchise guy."
Probably sounds crazy to some people, choosing Jeff Green over Carmelo Anthony, but Melo's just not a champion. A great scorer, yes, and a pretty good rebounder, but not anywhere close to being a complete player, and certainly not in the KG/Pierce mold of being a sacrificial team player. He's like Bad Kobe without the Good Kobe.
I'd rather keep Green and Rondo and try to find another star/cornerstone or two in the draft—either in the next couple years, or possibly one of the guys we already have, such as KO or Sully.
