Are you on PC?
If so, download cheat engine(google it). Start cheat engine, start 2K12, select nba2k12.exe process in cheat engine in upper left hand corner, then load the table.
And load the table file that can be downloaded in this post. Somewhere in the thread it tells you what values to actually use. It actually requires a bit of math, but nothing too difficult.
