Burks isn't a great defensive player by any stretch, but Jefferson...he's ****ing terrible. Dude ball watches like nobody's ****ing business. The Jazz are thin on the wing, so he'll get his minutes, but there's no reason he should be getting more than Burks (although this depends somewhat on what's happening off the court/in practice, I suppose).
Also, Kanter still isn't boxing out. What the ****? He just refuses to put his body between his man and the basket, choosing instead to try to push players with his arms, putting himself out of position to grab rebounds AND allowing the opposition to get wherever they want. Can anyone offer an explanation? Very confusing.
