People have mentioned that drafting is far from an exact science, and that's true to an extent, but over the past 30 drafts, if you group it into top5, top6-10, top 11-20 and so on, then the top5 group has yielded the most all-stars and most all-NBA (1st/2nd/3rd team) players compared against any other group.
What does this tell us about this particular draft? Not much.
However, it stands to reason that you are much more likely to find someone good at the top (particularly top5) rather than at the bottom. Yes, the draft is a crapshoot, but not THAT much of a crapshoot. There is some science that still goes into it, albeit not 100% accurate. Finding a Rajon Rondo, Tony Parker, Gilbert Arenas, Manu Ginobili, etc. is really more the exception rather than the rule. It's like hoping to land the #1 overall pick while holding a less than 5% chance. It's happened before (the Magic, Nets, Bulls and Clippers) and it can happen again, but odds are that it won't.
