Not if there are custom rosters. Paul George's trade value is considered 3 1/2 stars by the custom roster I'm using (OS Trifecta) and many others in my association. Paul George, IMO has more upside than Thornton, and David West is still that consistent 18 PPG scorer he was back in his days in New Orleans. I'd say you'd be making your team better, and with a core of I. Thomas, Paul George, David West, Cousins and Tyreke, that is one heck of a starting line-up. The only concern I'd have is defensively, where George is you only good perimeter defender and Cousins is you only good defender inside.
