From what I've seen, here are the top 30

Before ranking players on any Big Board, it's important to have a philosophy heading into the draft. Here are five things every NBA general manager should keep in mind:

• Everyone would like to wait till next year. So if you are not in love with what you see on your draft broad, go Chicago Cubs-style and "wait 'til next year" and its stellar draft class. While most NBA pundits talk glowingly about the free-agent Class of 2010, the college basketball world is smitten with the vast amount of returning talent in its game. Potential lottery picks Greg Monroe, Al-Farouq Aminu, Willie Warren, Cole Aldrich, Luke Babbitt, Jerome Jordan, Evan Turner, James Anderson, Kyle Singler, Craig Brackins, Ed Davis, Kalin Lucas and Jarvis Varnado will be joined by a much better freshman class (John Wall, Avery Bradley, Renardo Sidney, Derrick Favors just to name a few) in what surely will be a very deep draft. ESPN's Fran Fraschilla has called this year's draft class the worst in 25 years. Listen to those who know and get a pick from a potential lottery team for next year.
