Yeah that'd work for me, even if that gave Chicago a tiny ass window to win a Championship having Duncan on board. Only problem is, I hate both Parker and Duncan because they play for a team who fakes defense with their complaining and flopping.
Living here in Austin Texas I can tell you that the San Antonio fans would never allow the Spurs to trade Parker until he is about...50.
I don't really like the Spurs but I must give them credit for how loyal they are to their players. Honestly, (I know this is cliche but) they should have made some move to get younger sooner. They probally didn't because of how familial they are as team, staff, and the owner.
