And what are you going to do when the offense checks into a weakside run or screen/smoke route? There is a reason why teams don't do that.
again it is about uncertainty of what the offense will get, as well as the timing of the shifting.
i have seen teams do a great job at timing their shifts, but cowboys seem to be bad at it.
that is probably a marinelli flaw.
part of the shift pattern is back to the 4-3 where the RDE is in fact lined up wide 9 against a weak side run.
another thing is you dont always start in the 4-3, but also start in the 3-4
and part of the shift is back to the 4-3 which is played some of the time.
the main weakness is the weakside like u said, and you may bait a run in 3 and very long - that would be a scheme win.
and the S/LB that spy/delay blitz is someone who may be fast/agile enough to get around the LT like S or Jaylon.
also the DE will be in the LT-LG gap to help keep the LT busy.
but yes it is a race but that is the nature of an aggressive D.
will the a-gap guy and other guys get there before QB gets the ball away.
that is why i think we can play this D because our O is so dominant.
all we need to play this D is a OLB and a NT - 1st and 2nd round picks.
lets say offense responds.
question is what they can do.
they can go in shotgun, they can add protection, they can call for a screen
lets say QB is under center and he goes into shot gun.
then that makes a run less effective and it may be worth our while to shift jaylon from pass rush to drop back.
while screen is always a counter to a blitz, the 3 DLs are expected to occupy the OL to facilitate things for the blitzers, so they are not expected to have penetrated far beyond the LOS.
again we would play zone behind so there is a safety net.
and we may well have a 2 man advantage in defender vs receiver - i did the math before.
