I feel like some people on this board have unrealistic expectations of the kind of players available outside the top 5 in the NBA draft. There just arent sure-fire prospects available in the 8-10 range in the draft, you might be able to find a starter, but there are a lot of misses at this position.
Here is a list of the 15 players drafted between 8-10 over the last 5 years:
Starters: Brook Lopez, Demar Derozan, Brandon Jennings, Gordon Hayward, Paul George, Kemba Walker, Brandon Knight, Andre Drummond, Trey Burke
Rotation players: DJ Augustin, Jordan Hill, Al-Farouq Aminu, Jimmer Fredette, Terrence Ross, Kentavious Caldwell-Pope, CJ McCollum
Busts: Joe Alexander, Austin Rivers
I think I was pretty generous with these groupings, and some of these guys are getting a lot of minutes because they play for poor teams who are hoping they will develop with enough playing time
