Relative Value of '08 Draft Picks

Where would you slot this year's picks in your minor league rankings? For example, how would Tim Beckham compare to Elvis Andrus?

Another interesting thing to consider is where non-draftees (e.g. players who signed at a young age) would go in this year's draft. For example, how high would Andrus or Angel Villalona go were they eligible, given what we now know about them?

I look forward to reading your responses. Thanks.
