80-100 range. He's never going to be a top 50 type because he lacks the requisite athleticism, but he has dog in him all day.
I said it a few posts above, best case comparison is Jordan Taylor. An undersized Chauncey Billups type
I can guarantee that nobody will outwork Dave. I generally hold workout sessions for some of the top players in the Detroit area, and this kid works out 2-3 times A DAY, for 1.5-2hrs a session. His will to be great is tremendous.
Dave is just a great kid, period. 3.9 GPA as well. Does charitable work. Came to see me at the hospital late at night before a school day. He's just a perfect fit for Michigan across the board.
He literally called me in tears when Eli committed because he didn't think he'd get an offer. Fast forward a few months and Dave is a Wolverine!
