Not sure if this has been mentioned before, but one useful addition could be integrating a "tactics algorithm" in the game. Mainly in Career mode.
If I am batting at no.4 or if I have batted long enough, I should be able to tell my batting partner to calm the hell down and not hit risky shots. Or if its the last over the match with 10 runs needed, I should be able to tell the tailender on strike to try and get the strike over to me (if I am the set batsman). It wont be easy to balance something like that, but if done well it could take the already-brilliant mental aspects of the game to a whole new level.
Could be controlled by the d-pad keys during the game - something on the lines of how we set offensive-defensive tactics in FIFA.
