Now, back to Derryck; I was the one calling out your small sample size of knuckleballs and examples, now you're coming around. The kid is 20-50 from 3, playing with a tight "lease" as PG. I've seen him shoot plenty enough to know he can (see the 50 shots above and plenty of video and 2 games I've been to, especially watching him shoot beautifully before the Elon game). Can he improve his shot? Yep, he can get to 50%, or maybe 100%, but considering he's a late-developing Freshman (regardless of HS year and numerical age), averaging 8.2 ppg, and has basically won Duke two games this year, I'm happy with where he is. As I stated above, others have been on your arse here for the negativity, and it's painfully obvious why.
As for Frank - kid is a stud, but he doesn't have true PG skills yet, not for college anyway. DT will be improved in year 2, and will have the job on lockdown next year.
