I think he HAS to do more than manage the game. This team isn't good enough to win with a manager. They will be down, and will have to open it up out of necessity.
I think "managing" is the absolute worst approach for him at this point. I think he needs to make big plays, and learn how to manage as he goes. It will be an erractic season of ups and downs, but this team isn't going anywhere special this season anyway.
I expect him to throw the ball around like a gunslinger whether the coach likes it or not, because that is Allen's instinctive response.
I expect him to throw an interception or 2.
I expect the running game to be much more effective because the opposition won't be sure to commit to stopping McCoy.
I don't know if they will win, but I feel they will be a lot better.
