in real life, nba teams send younger players to the d-league, usually becuz the players arent getting the minutes in actual games that they need to develop. when a player is "assigned" they are still under contract, so NO other nba team can take them from you, however, nba teams do not OWN their affiliate. So, any player who isnt on "assignment" is fair game to any nba team for whats called a "call-up" in 2k call-ups work just like free agency, you sign a player to a contract and he becomes available to your team. in most cases you will not see a significant difference in ratings becuz you sent a player to the d-league, at least, i know in 2k10 that never happened, im not sure why becuz thats what the d-league is for but ive never seen anyone get better from it "in game"

hope that helps!
