I found out that if you lock coach settings with cheat engine tablet you can have playvison in mycareer...
1st: Downlead this http://forums.nba-live.com/downloads.php?view=detail&df_id=3587 and you must have Cheat Engine 6.2
2nd: Start the game then cheat engine then load tablet.
3rd: DONT start/load mycareer, go to your setting for playvision then adjust to your liking.
4th: alt+tab then lock values in CE tablet (mark only the ones that you need under coach settings with X)
5th: Start/load mycareer and enjoy playvision
ps: This CH tablet has many uses
