2K13 sounds exciting with all the rappers in the game, Justin Beiber, more hip hop flavor. (That was sarcastic).
It does sound exciting with the changes to controls and player momentum.
Are there tweaks or improvements to Association? For example, will some teams still carry 3 and sometimes more 80+ rated players at the same position?
Will play calling without the ball be restored, or will it remain that only if the player you control has the ball you can call plays? It's no big deal unless playing locked onto one player. It makes sense in legend mode, but not in association.
