MyCareer Help. Mod Player Draft Pick

Hi ! Guys I'm preety new here and still a newbie in playing Nba2k14 . I've found some mods like Kuroko no Basket and i've notice that in some teams their are member of Generation Miracles while using that modded MyCareer but when i use a normal MyCareer Account I can't find them
Now I'm asking on how to add customize player in draft lets just say i want to put the KNB players in others team using a normal Mycareer (created in my PC).
Can you help me guys please
