lol... in general:

I remember one year Joe Forte averaged like 20 points during the summer league. I remember Brandon Hunter averaging 16 and 8. Sure, if you're a good player you'll probably put up good stats, but good stats does not equal good nba player. Take them with a grain of salt.
In 2009, Anthony Randolph had summer league averages of 27 points, 8.5 rebounds, 3 blocks, 2.2 steals and 1.3 assists while shooting 61%. In one game had had 42 points. To be fair, I actually think Randolph has a great future with the right team... but take it for what it's worth.
Every year people get overly excited about some random 2nd round scrub (a Gabe Pruitt, Orien Greene or something) getting big numbers in summer league. Hopefully Sullinger ends up a real player, though. BTW... if Fab Melo can't even get 15 minutes in Summer League... what does that say about his current level of basketball ability? That's pathetic. Hopefully it's just so we can showcase JaJuan Johnson/Moore/Joseph for a Courtney Lee trade.
