I've been messing around with this play in practice. It stops the FB dive almost every time and it also is a nano. Although I've never used it online it seems like it would work well.
Setup: Pinch your line and re-blitz your first DT(guy that lines up behind center) and LE. Take the guy in the yellow zone and put him between the first DT and LE. Use the MLB and blitz between your two DT's. Make sure your in the package: 46 swap
