I for one am in the boat that feels that Lance would have broken out regardless of being a starter or not. Many forget the Bobcats game early in the season (2nd game?) when he came off the bench and showcased his ability in much the same way he has as a starter.
As for Paul George, if he is indeed a star in this league, he would have been able to be a star WITH Granger in the lineup as well.
Losing a guy who is an annual 18-20ppg scorer from your line up who is also taking up 13+ million dollars in cap-space is NEVER a good thing IMO
