Eh, I just don't see this as a career-ending or altering injury. By all accounts, it was a clean break with no damage (at least of any significance) to his nerves and muscles. He was also spared any damage to avascular areas, like ligaments. It was as gruesome to see as the Livingston injury without having even nearly as terrible a prognosis (remember, amputation was initially discussed as a possibility for Livingston).
I think they're willing to wait. They just invested $90+ million in the guy and he's their franchise player (for now). Using the Granger injury as precedent, they're not big on making such major trades without seeing how the player returns to form. Their best shot at winning a title - or even an extended playoff run - undoubtedly involves a healthy George, so I simply can't see them even giving the idea of trading him right now any consideration.
