couldn't tell. I tried going playaction fairly often, and there were not openings deep. I could occasionally find small 5-8 yard pickups over the middle if I had time in the pocket (infrequent), but the D was a little too good.
The thing that really bothered me about the defense was he would pinch his 3 DL inside (lined up over the guards and center), and yet half the time the DE would still pull off a crazy speed rush around the outside.
I like to use my 1-5-5 at times, but I don't consider that quite as cheesy, as that formation is used at times, even in the NFL. It's basically just a 3-3-5 with two LBs at DE.
