From Chad Ford's Mock Draft 6.0 (Insider):

For what it's worth, Cauley-Stein has been reportedly working on his jumper heavily this offseason in preparation for the draft and he's known as a hard worker in general. He improved his Free Throw Percentage from 37.2% as a college Freshman to 61.7% last year as a Junior. That's still not a great number but it's a remarkable improvement in the span of two years and with more work that number can grow even more respectable.
