The thing is, I was fine with the way it used to be. I've had my fair share of games where I was upset by lesser teams and beaten by lesser players. That's also where working sliders really help.
But yeah, you're spot on about the blitzers just walking right on through while the linemen turn in the wrong direction. I don't mind it sometimes, but it seems to happen more often now than it did in the past which is just unacceptable.
