Fantasy related: ranking the 2009 draft class for immediate impact (college only)

Say you only get to keep a 2009 draftee from 2010-2013 before he becomes a FA, how would you ranked the top 20 players from this year's class? Assuming 5x5 (or add walks for hitters if it makes a big difference).

1st 5 picks in our fantasy draft if it helps...

#1) Stephen Strasburg

#2) Aaron Crow

#3) Dustin Ackley

#4) Grant Green

#5) Michael Minor

Don't have to pick from this list, but these are some of the better options I could come up with...

White, Alex
Leake, Michael
Sanchez, Jorge
Storen, Drew
Green, Grant
Pollock, Allen
Jenkins, Stephen
Gibson, Kyle
Mitchell, Jared
Arnett, Eric
Jackson, Brett
Wheeler, Timothy
Brothers, Rex
Scheppers, Tanner
