UPDATE on Weds, July 11 at 1:30 p.m.: This trade has been expanded to include Jarrett Jack coming to the Warriors. Click here for the details on that deal.
Avinash Kunnath of SB Nation Bay Area has already described what the Warriors gain from this deal, even if we don't know who that player is just yet.
The Wright deal pretty much opens up the small forward position for rookie Harrison Barnes to take over the starting small forward spot. It also opens up more opportunity for Brandon Rush, who's coming off a career season where he averaged nearly 10 points per game in an average of 26 minutes of action, but also while shooting 50% from the field, 79% from the line and a pretty incredible 45% from three point land. With Wright's four-million dollar contract out of the way for next season, Golden State should be in a pretty good position to sign Rush to a deal similar to the one Wright had and still have room for more free agency moves.
Tim Kawakami has tweeted that the move gives the Warriors salary flexibility to re-sign Rush and still "also sign another player or two."
As for that anonymous player, Michael Levin of SB Nation's Liberty Ballers suggests that it's possibly Edin Bavcic.
