Again, look for some precedence -- has there been ANY team in the league that traded OUT of the Top 3 (much less, the Top 5) to get 2 role players and a former top 2 pick who has underachieved the pass season or two?
Let's check:
2012 - no trades out of the top 5
2011 - no trades out of the top 5 (even though MIN tried valiantly to trade out of #2)
2010 - no trades out of the top 5
2009 - one trade out of the top 5 -- MIN acquired the 5th pick for Randy Foye and Mike Miller (an unprecedented stupidity).
2008 - MIN and MEM swapped #3 (Mayo) and #5 (Love)
2007 - BOS traded their 5th pick for a 32 year old (but still productive) Ray Allen.
2006 - CHI and POR swapped #2 and #4 pick
2005 - POR moved down 2 spots, from #3 to #6 while getting 2 picks. (I was mistaken, there was! POR moved OUT of the top 5, into the #6 pick!)
2004 - Washington traded Devin Harris again (#5) for Antawn Jamison
2003 - no trades out of the top 5
So I think the going price for a team moving out of the top 5 is either -- a league known contributor (Allen, Jamison) or that Deron Williams trade, which if I remember correctly, POR did because they were still confident that Sebastian Telfair (their 2004 draftee) would pan out and they had no need for Deron, CP3 or Felton (sorry, just LOL'd a little bit). Can you say the same for CLE? Can you say that they have no need for anybody available in that range? Otto Porter? Nerlens Noel? I doubt. If McLemore was the only player available at #3, sure (which I doubt happens). But even then, I don't see how they trade down six spots to get damaged goods in Derrick Williams (and I think everybody will agree he is damaged goods).
