Yes, he is presently a bad shooter. Scoring .9 points per shot. That's bad.

Though it's worth noting that Mario Hezonja, from the same draft, taken 3 spots above Winslow, is currently doing .87 points per shot. Also bad. (Especially since his rep coming into the draft was as a shooter.)

But Winslow is 20 and Hezonja is 21. I'm not convinced either will be the worst ever at anything. Austin Rivers was called the worst player in the NBA by plenty because he couldn't shoot at age 19/20, and now, at age 24, he shoots over 40% from 3. *shrug*
