You are undercutting the point total. Locke did this on his show today or yesterday in that you have to factor in the Quality of shot as well. Both Rubio and crowder got 52 and 55 percent respectively QOS. That makes their actual percentage a lot worse. I think Conley and Bojan were between 48 and 50 percent and they overperformed significantly.
The measurable point differential on offense is going to be higher, probably MUCH higher, than 2.34 point per game. Even if teams work to limit shots of Conley and Bojan, it is just going to raise the QOS of Spida, Jingles, Royce, and Rudy. All of those players have shown what they can do with room.
