Cog in the machine. People don't understand how much we use him as a decoy. He's almost always part of any Wemby/Fox pick & roll action, screening and then popping out to the 3-point line. Teams know they have to guard him tightly, so he just creates a ton of space for those 2 by moving off the ball. Then when teams focus on shutting down Wemby/Fox/Castle you can just ride Devin. What are they gonna do? Put Duncan Robinson on him?
Also if there's one good thing he learned from Kobe, it's showing up in big games.
