I have NBA Live 10 demo and noticed that graphics file formats are similar to NHL games which I can edit with a tools I made for NHL textures. I think some might be interested this. I tried to add modded stuff in retail console but didn't succeed so if you don't care about LIVE I recommend rgh modded console for mods. I wrote a tutorial for NHL Legacy jersey modding here:

To view textures you need Noesis: https://richwhitehouse.com/index.php?content=inc_projects.php and rx2 script in attachment (extract zip and put the script in plugins/python folder.
