I don't know if this is true. In 2k10, it was more of a grind. You had summer league, training camp, and d-league. If you weren't good enough you played in the d-league. I remember all the complaints about the process and that they didn't want to have to go through all that. There were a lot of complaints. So 2k went into a different direction and made becoming a star easier.
This year it's a bit of a grind, but there is no training camp, summer league or d-league in mycareer. I loved the setup of myplayer in 2k10 and 2k11.
