You mean the lack of spacing AI? PG's playing dribble games at the 3pt lines? Centers hitting 20ft fadeaways from the post? The list goes on and on
The playbook that people edit and remove most the broken plays from? The same playbook that ends up only having a few plays used cause the rest are broken? Or the AI getting confused what to do on plays so they just hold the ball for 24secs and jack up some shot cheese?
Since 2k11 gameplay has been mostly ignored, it's hard to sell "gameplay" as a new feature to make the box stand out every year.
