Koufos is just one of many that we've either traded for nothing or just let walk, and have turned into decent NBA players.
Koufos
Matthews
Millsap
Korver
Carroll
Jefferson
Humphries
Koufos I could understand, still not a productive player post trade. Kris Humphries had years to develop and in my opinion never did. His highlight is banging a Kardashian broad. The rest we could have at least made an effort.
There have been many drafts that we have failed on more than we won.
1999 Scott Padgett was drafted ahead of Manu Ginobili
2001 Raul Lopez was selected in front of Jamaal Tinsley, Gerald Wallace, Samuel Dalembert, Bobby Simmons, Mehmet Okur, Gilbert Arenas and Tony Parker
2002 Curtis Borchardt was selected in front of Luis Scola, Nenad Krstic, John Salmons, Matt Barnes, Tayshaun Prince and Carlos Boozer
2004 Kris Humphries was selected in front of Al Jefferson, Josh Smith, J.R. Smith, Jameer Nelson, Tony Allen, Kevin Martin and Anderson Varajeo
2007 Morris Almond was selected in front of Aaron Brooks, Arron Afflalo, Tiago Splitter, Carl Landry Glen Davis, Ramon Sessions and Marc Gasol
Keep in mind that even though DL is the GM, KOC is pulling the strings behind the scenes as President of basketball operations. The same guy that failed to recognize talent while these drafts were taking place that I listed above.
