We could still trade away Harrington and try to preserve Lee. Although Harrington is a decent player his consistency is lacking and personally I just don't rate these "bigs" who can't post up and only shoot from outside.
However it would have to be Harrington + Chandler + Nate or something, to make the contracts match, or get a third team involved.
I doubt Amare is attainable sadly. And you're right, the return we got for Zbo and Crawford was pretty negligible. Harrinton, ok... Not too bad, Tim Thomas and Mobley? Sigh.
