Duke hasnt had his athleticism plus he is 6'8".That's a big add for dook. Of course, he won't contribute this year, when they could really use him most. But it's as good as adding a top-20 recruit for next year.
Then again, he's basically the same style player as everyone else dook gets these days. He won't help them break the mold. And until they do that, they are predictable and exploitable. I don't fear them anywhere near as much as I once did.
I have seen him talked about as a top 10 NBA pick after his soph season.
