All great shooters spread the floor, but nobody does it better than Ray. He is the guy the defense has to stay attached to more than any other. He runs and runs and runs, moving without the ball constantly. Teams game plan as much for him as any other player on the Celtics.
We need Ray, especially at his $10M salary. If you look at what other elite shooters make, he is a bargain considering he is the best.
If we were to move him, it should have been at the deadline last year when he was making significantly more ($20+ million). Ainge stuck with Ray then and I don't see that changing now.
Rondo is the only one of the Big Three Plus One I can envision being moved, but even that seems unlikely unless CP3 really wants out of NO.
