Only way i can think of is to try through the NBA itself. I know there are quite a few former players on team staff lists, so that would be a start. Ewing is the Assistant Coach at Orlando, Detlef Schrempf is on the recruiting staff for portland i believe, Avery Johnson Head Coach at Brooklyn....
Collect Patrick Ewing, Jalen Rose, Kevin Garnett, LaMarcus Aldridge, Jeff Green
if you have less than 25 trades, I will ask you to send first.
