Thinking about what Brooklyn would be willing to do to jumpstart a legit rebuild:
JJ and Lopez
for
Wallace, Thornton, Bass, AB and their 2016 and 2018 (we keep the 2017 swap)
The numbers are fairly close -- we'd have to come up with a little more salary I think (not much).
Our roster:
Rondo, Smart/Pressey
JJ, Smart, Turner
Jeff, Turner, JJ
Sully, KO
Lopez, Zeller, KO
Could swap Lopez for KG in the above making the salaries close to perfect. Less of a salary gain for Nets for 2015-16 but gets them their lotto picks back and free from JJ's salary one season early. Probably could unload Lopez elsewhere. Gives us a year or 2 with KG playing 20 MPG and mentoring our young bigs.
Not sure I love either scenario, but somewhat interesting to think about.
Also could look at getting Garnett and Lopez and keep AB (or Bass):
Rondo, Smart/Pressey
(AB), Smart, Turner
Jeff, Turner, (Bass)
Sully, KO, KG, (Bass)
Lopez, KG, Zeller
I'm terrible at this trade thing. Not sure why I let myself go there.
