Is it possible to edit default NBA 2K11 players (on PS3, if it makes a difference)? For example attributes such as physical appearance and skill level? If so, how can I know if any of the following have been altered (is there a file that is created that I should look out for)? How can I revert back to default NBA 2k11 player settings?
My little nephew loves to mess around with things like this and I don't like it

. I know in Fifa 09, for example, you can go in and reset roster and all goes back to default.
