I've actually thought pretty hard about this question, but I can't find any good reason to consider Lopez. He's got a nice scoring touch and will help on the boards, BUT he is not a great defender and low post defense may be this teams greatest need. Then add in that he is a bit older so can't really be considered a key piece in a rebuild. (Young core: Bradley, Smart, Young, Crowder, Thomas. I would trade Sully and/or Olynyk as they are attractive to other teams. Bass is the salary fill.)
Finally, Brook's the injury history is scary.
No thanks.
