I doubt the Zero Tolerance policy affects Sheed's attitude toward officials. Sheed has received 257 technicals in his career. It's probably safe to say he knows what is not allowed. He pushes the officials to the edge, and then when he is feeling selfish, he pushes a little bit further. I'm glad Sheed is a Piston, but getting technicals to the point where it will hurt your team (game suspensions) is purely selfish.
