Update player models?

I was wondering if there are any patches to update the player models. Like updating the looks of the players. For example, Carmelos hair style. His default hair style is braids and now his hair style is different. Ive seen screen shots with the new player models wondering where i could find them.

thanks

You can find many custom mods in the NBA 2K9 Patch Releases and Previews section of the forum.
