I think that's part of it, but the OLine seems to get such a huge push on the DLine when I'm rushing, when in fact they should be dead stopped, uneven (as in both directions), or even going backwards. The effect is when you go the opposite direction they push the defenders away from the way you are running, thus they are immediately there. I see what you mean about suction though. In reality, if the blocker was going left, and the defender was going straight, they would ignore the blocker and keep on going, not engage the blocker. Yuck. I'm not going to use 'em. That just doesn't seem right to me. I'm weird that way though.
