you cant dude... thats the problem with this game. i have tried eveything possible. best thing i can tell you to do is to 4-4 cover 3, squeeze your line, stretch your LB's, user control your free safety, and audible him to man cover the opponents RB so that when he snaps the ball your safety wont get f'd up when he calls counters. it is important to NOT PINCH your line down. only squeeze them. pinching will not let your D line expand to help seal the edge, however squeezing them will allow them to better stop the iso's and power plays while still allowing them to get to the edge. you need to use this in conjunction with the LB2 button guessing which way he will go by his tendencies. only do this when you think hes going to sweep, or power. and only use the LB2 sparingly. at best this strategy will slowly walk you down the field with a few opportunites to put him in a 3rd and medium or 3rd and long situation. it is important to capitalize on thes VERY FEW opportunites because the POWER OFFENSE IS WAY WAY OP THIS YEAR...
