This is a pretty simple trade, I'm not to sure how willing GS would be to move Barnes.
Lowry, Our 1st rounder in 2016
Barnes, Toney Douglas
This trade will give them a backup PG for the often injured Curry, and with AI and Green they have enough wings. The first rounder sweetens the pot, but I still don't think it's enough. I'm not willing to move a 2014, or 2015 pick and the 2016 pick is expendable because we have New Yorks pick that year.
Amir (FA or draft pick)
Draft Pick, Free Agent, or Vasquez
We have a ton of flexibility this upcoming year with draft picks and cap relief. If we have Barnes we could easily target a starting PF or a PG. IMO this is a good young core going forward.
