come out of a play called zero blitz(man coverage) you have to set this play up fast as hell or else it won't work
Pinch the Dline down
Blitz all the Dlinemen
Blitz down both blitzing LB's, and put them between the RE and DT, and the LE and DT(make sure there closer to the DE's than the DT)
control the blitzing DB and play deep coverage.
