I would absolutely do it, no brainer. With Smart we already have a legit staying PG for the future, and Hill would give us a fantastic backup PG for years to come. Given that we already have the risk of Rondo leaving us for nothing next year, this largely offsets the risk of taking George. If it doesn't work out you've really not given up that much, because we all have a young PG with future all star potential in Smart.
A roster of Smart/Bradley/George/Sully/Zeller (or Olynyk) has a ton of potential.
On the flipside I seriously doubt Indiana would do it...Derek Rose has been the NBA equivalent of a corpse for 2-3 seasons now and Chicago still haven't traded him away. Portand held on to Oden for years before eventually giving up on him, and held on to Roy until the day he retired.
Teams have a tendancy to hold on to guys like George.
But if the deal did come up, I don't think DA would need to think very much. To be honest a Rondo/Green/West/Hibbert starting lineup would be pretty solid of they can find a Guard that is worth of starters minutes. Maybe Boston could throw Thornton in there too and take back a pick.
