actually 4-3 defenses need to have flexible lines that can do what the particular assignment is for a play whether it's rush the pass or help linebackers make plays on the run
it's not the 90s anymore. if we've learned anything from having kemo play for us it is that you need to be able to do more than just one thing when you're in there to be effective
this is true, also in a JJ scheme defense the 3 tech is still supposed to be a penetrator and disruptor. and just cause you are doing those assignments doesnt mean you are not still taking on multiple blockers to free up the LBs. in a passing situation you want to get a push from the inside and not have your DTs just taking blockers on.
Last season, I watched Jim Johnson’s defense sack Ben Roethlisberger 9 times in a 15-6 Eagles win. Johnson understood that when there was a single high safety in coverage, the Steelers were not going to account for a blitz from the slot since there was nobody who could cover the slot WR if the Eagles were to blitz. Instead Johnson came up with a blitz package that gave the Steelers fits and forced them to change some of their protections in the future to prevent other teams from doing the same thing to them.
* Notice that Johnson’s defense would crowd the LBs into the “A gaps”. He knew that Pittsburgh would have their center block the LB to the right and the running back was responsible for the LB on the left.
* You’ll notice that pre-snap, there is no help for the CB who is coming off the slot on a blitz.
* Johnson would blitz the LB on the left which forced the RB to step up and pick him up, but he would have the other LB sprint to help cover the slot WR. Johnson created a scenario where the slot CB would fly in untouched.
found a simple blitz that i do remember us running some last year that shows the 3 tech is still providing penatration from the inside and the CB/nickel guy coming on a blitz from the outside. which i think Captain does best and since i think he is a liabilty in coverage he will keep blitzing from the nickel spot unless he gets beat out.
