Yup, confirmed. Monster green out of 3-3-5 split duplicates this. Manually blitzing seems optional. You get plently of good heat having the cpu blitz and using stick skills for coverage. I always forgot to use it. I noticed I have a much easier time having the MLB hit the T on the left side of the TV screen. This causes either the T to block the MLB or the SS letting one of them free to hit the QB (sometimes they both come in untouched). You can get around the T with the SS only but this way is more guaranteed if you screw up on the around around the T, which kills this play if you miss.
Also, if they slide protect to your SS blitz side, just run the play base and you get a nasty natural nano from the opposite side. Still user the SS to make your opponent think your running the play again but just run it base with the same adjustments you have less the LB zone audible. They will slide protect to your SS thinking your coming and maybe even put a RB to block that side, but the heat will come from the opposite side VERY quick.
It basically allows you to nano left or right depending on what your opponent does. I love plays that look the same but bring the heat in different ways on D. Totally screws with your opponent lol.
