KD is set to be re-evaluated in 3 weeks, it isn't for sure he is returning by then. Westbrook might have 3-4 weeks left however they are in a very, very talented and deep Western conference. I am not sure any teams could afford to go on a huge hole in the beginning of the season in the West.
As for the Pacers, I am not sure George Hill will be back at the end of the season but even by then it might be too late and he might be better off resting than risking it for a small chance to get into the playoffs. With that said, the East is pretty weak so they can take advantage of that but they really need to stay close to .500 so these bench guys needs to really pick up the slack. Not sure how long Hill and West are gon' be out either. Hibbert needs to start playing like an actual All Star too.
