Since everyone on the board is so reactionary to calling Fab Melo a bust or crown Perry Jones III, I decided to do a little research.
Just so people temper their expectations a little bit:
2003 Reebok Summer League Leading Scorers
1. Donny Marshall, NJ - 20.0
2. John Salmons, Philadelphia - 19.6
3. Juan Dixon, Wash - 18.0
4. Kedrick Brown, Boston - 17.2
5. Brandon Hunter, Boston - 16.3
6. Lebron James, Cleveland - 15. 3
2004 Orlando Summer League Leading Scorers
1. DaJuan Wagner, Cle - 18.6
2. Jarvis Hayes, Wash - 17.8
3. Tony Allen, Boston - 13.4
4. Al Jefferson, Boston - 13.0
Now granted I didn't post every season here.. but, you get the point. You can't judge a player to be successful or unsuccessful in the NBA based on their summer league stats.
