Where on the court isn't Lillard proficient?

From Erik Gunderson:

"Lillard's work pays off

Damian Lillard is shooting 68 percent from less than three feet according to Basketball-Reference. Over the last two seasons, Lillard has never shot better than 53 percent from that distance.

Lillard is taking a near identical percentage of his shots around the basket. He's just been much better at it and lots of summer work is paying off.

"Going up to the rim and getting hit with pads and stuff like that," Lillard said of the summer workouts to improve his finishing. "Playing against contact. Sitting down in a the chair then just coming out, getting pushed and still trying to come out and finish. It's just paying off."

Other techniques such as getting the ball higher on the glass, Lillard says, have helped improve his finishing.

Despite Lillard, the Blazers are in the bottom-five in points in the paint."
