This one is bad.
When an offensive player is near you, he can automatically engage you (in a blocking stance) no matter where he is with respect to you, and you must break free of the block before moving on.
Situation: leading Kansas 6-3, third-and-6 at our 8. Toss play to the right. I cut inside the receiver as I see it's a run and move to cut off the RB. As soon as the RB catches the pitch, I turn away from the RB, who is in front of me and slightly to my left, and move to engage the WR, who is still behind me and to my right! Turning so my back is completely to the play I had just successfully identified. To make matters worse, even though I want to get to the ball carrier who is behind me, I am stuck on the guy in front of me. Naturally, because I'm the CB, no one has a pursuit angle and the RB scores easily.
What is this crap? Offensive players carry mind-control rays that prevent you from moving in the direction you want to move? No wonder it's so hard to play defense in this game.
Congratulations, EA, you've crapped all over yet another successful franchise.
EA Sports. It's not in the game, we put it there because we don't test our games any more.
