This is probably a horrible thing to do but it helped me pressure a guy into a bad into on the last drive of the game for him.
Well I did this with the Titans controlling the FS. When my d line walked up to the line i shifted them before they got into the stance with an arm on the floor. I was planning on blitzing to the side without a TE so I shifted to the left. Before they got into position the ball was snapped and I almost had instant pressure sacking him. To try it again I did the same. My D-line never got into stance so their were strafing from left to right to keep them standing upright. This time however he got a bad throw off which i user picked so I could end the game. My best guess for this is that hese constantly shifting his O-lines blocking. I tried it against the CPU and I got alot of pressure with about 3 sacks.
Can Someone else try this and see if it works. Though dont let your D-line get in stancekeep them upright by changind direction.
