Wilson Chandler is the most likely trade target. The noise right now is about Arron Afflalo, but Chandler is a. an easier contract to move and b. a more reasonable asset to trade (as in, you don't need to get huge return for him vs. Afflalo with All-Star potential). The Blazers have been chasing Chandler for months,
and CSN Northwest reports they're ready right now to give up Thomas Robinson, a first-round pick, and "another player" for the wing. That "another player" is the likely hang-up, with the Blazers thinking C.J. McCollum and the Nuggets likely wanting Nicolas Batum (that's been rumored but not reported as the scenario and it makes a lot of sense).
