Loose, +1 for the premise of the thread.
With George out at least this year and Indiana all-in with West and his brief 2-3 year window, Bird either has to let West go, tank and build for when George gets back or add pieces to compete now with West.
One thing to consider is that David West is the heart and soul of that team with his toughness and experience. If they dump West now after having dumped Granger last year, that locker-room, which was fragile last year because of the personalities and the alleged George/Hibbert fiancee thing, could be damaged for years, especially if Hibbert stays, which is why i like your trade idea. Hibbert and West go together, and they build for a George-centric future. We compete now and they compete later.
The other option, competing in West's brief window, is more problematic. Pacers need scoring on the wing and some star infusion. The main problem is that aside from the core of West/Hibbert/George, they have little to trade to acquire those valuable commodities.
If they want to compete now in West's window, all they really have to trade to get those assets is Paul George, and everyone says that he is untouchable. If so, they cant legitimately compete now.
However, if they, in the highly unlikely scenario, decide to trade George (compound fracture in two places takes a LONG time to heel, never mind the muscle issues associated with it), Bird may consider Rondo (star pg), Thornton (desperately needed scoring from the wing) and Green for George and Hill.
What a defensive team that would be with Rondo/Green/West/ Hibbert.
