Here is a list of all the Summer League MVPs. Interesting who rises to the top, and the group that JV just joined.
2013 - Jonas Valanciunas (age 21)
2011 - lockout
2010 - John Wall (age 19)
2009 - Blake Griffin (age 20)
2008 - Jerryd Bayless (age 19)
2007 - Nate Robinson (age 23)
2006 - Randy Foye (age 22)
Summer league doesn't really say much, but I'm hoping he falls into the Lillard, Wall, Griffin category.
