Many former NBA draftees, waived players and undrafted players have played in the NBA D-League. Some of the called-up D-League players that went on to have successful NBA careers include Rafer Alston, Louis Amundson, Chris Andersen, Kelenna Azubuike, Matt Barnes, Devin Brown, Will Bynum, Matt Carroll, Eddie Gill, Stephen Graham, Jason Hart,Chuck Hayes, Anthony Johnson, Dahntay Jones, Jamario Moon, Mikki Moore, Smush Parker, Bobby Simmons, Ime Udoka, Von Wafer, C. J. Watson, and Mike Wilks.[17] Aside from these players, there are several successful NBA players who were assigned to the D-League in their first and second season, such as José Juan Barea, Brandon Bass,Andray Blatche, Avery Bradley, Aaron Brooks, Jordan Farmar, Shannon Brown, Marcin Gortat, Ramon Sessions, Jeremy Lin, Danny Green and Martell Webster.[18]
Bobby Simmons and Aaron Brooks are the only former D-League players to win an NBA end of season award; Simmons won the Most Improved Player Award with the Los Angeles Clippers in 2004–05 and Brooks won the Most Improved Player Award with the Houston Rockets in 2009–10.[20][21]
And as a Bucks fan, I know that Larry Sanders played in the D-League for a little bit. Doron Lamb has been in the D-League a decent amount. Jeremy Lamb, Fab Melo, Reggie Jackson, Tyshawn Taylor, Donald Sloan, Jon Leuer, Andrew Goudelock, and a few others have been bouncing between the NBA and NBADL this year.
Edit: So the guys that were able to stick in the NBA were:
Rafer Alston, Louis Amundson, Chris Anderson (Birdman), Kelenna Azuibuike, Matt Barnes, Devin Brown, Will Bynum, Eddie Gill, Chuck Hayes, Jason Hart, Dahntay Jones, Mikki Moore, Smush Parker, Bobby Simmons, CJ Watson, JJ Barea, Brandon Bass, Andray Blatche, Avery Bradley, Aaron Brooks, Jordan Farmar, Shannon Brown, Marcin Gortat, Ramon Sessions, Jeremy Lin, Danny Green, and Martell Webster.
Amundson, Birdman, Barnes, Bynum, Hayes, Dahntay, and everyone listed after Simmons were all pretty successful.
