No it does not happen from time to time, it happens every time. I use the Chiefs and I take control of DL Glen Dorsey. Every time I get through to the QB he all of the sudden becomes a super human and rockets the ball out before I can hit him. Some times he will throw and INT but most of the time it's a completion that would never happen in real life.
I do not dislike Madden 09, I agree it's a step in the right direction, but for you to defend the Robo QB in the game is a waste of your time. It's there and it's a game killer.
