I agree, the AI definitely picks up on tendancies. I, too, like to put players in motion (usually a 2nd or 3rd tight end) on power running plays to get an extra blocker at the point of attack. When I first started doing this a few weeks ago, I was killing the CPU (using DB's custom sliders), but now the technique is much less successful. I can still run the ball well (using the Falcons/Turner), but the CPU is now much quicker to put 8 in the box to stop my running game. I have to be able to pass the ball effectively to keep it going.
