Screens and outside runs can be a real problem. But you can contain this nuisance farely easy. Its all about D-LINE play.
Try it your self.
SLANT your defensive line in the direction where you believe the slip screen is coming. VOILA. Play stopped. lol. That simple. Go to the practice field and check it out. You really want to have MAN TO MAN DEFENSE BEHIND IT, but it some cases, you can get a way with zone. BUMP AND RUN AS WELL.
There is so many ways to stop this.
The best thing about outside runs and slip screens is that they attack outside the tackle. So what you need to do is simply learn how to attack outside the tackle correct?
Slant your D-line in that direction...
The play starts, and notice how instead of your defensive lineman attacking the quarterback on the screen side, THEY FOLLOW THE OFFENSIVE LINE TOWARDS THE SCREEN. Play over and done with.
If you really really want to get a MORE firm grip of stopping the slip screen, you can not only SLANT your d-line to the screen side, but you can also SHIFT your D-line to the play side.
I suggest only slanting your d-line to the screen side, and NOT shifting, because then your opponent will notice that you have defenders attacking the screen side, and they will simply audible.....
So if you ONLY slant them to the screen side, and NOT shift, you bate them into not audibleing out of the screen play. Right into your TRAP.
Well how do I know which side the slip screen, is coming on you ask?
If there in shotgun, very simple....Its on the same side as the Running back obviously if its a slip screen.
But If there in singleback and you sense a slip screen coming.....Then you have to go with tendencies.
Have they been throwing the screen on the wide side of the field all game?
Does he throw the screen on 3rd and short?
Does he do a major personnel change everytime he throws the screen?
He seems to never audible when he throws the screen?
Go with probability also.
You can also Playmaker contain your DEFENSIVE TACKLE on the slip screen side.Make sure you do this after you slant your d-line to the call side..not only will he follow the lineman, but he will play outside the running back, which keeps him inside if he actually catches the ball in all that traffic, and this forces the running back towards defensive help.
Now, if it turns out that the running back ran the slip screen to the opposite side of your slanting d line...you would be in BIG TROUBLE....BUT....
to counter you guessing wrong on the play side, contain the defensive end on the opposite side to contain on his side. He will follow the offensive lineman instead of attacking the quarterback, while your other lineman will rush the quarterback due to them being on the wrong side. Play still contained.
Disadvantages and advantages with everything of course.
The big disadvantage is if you guess COMPLETELY wrong on the play call...and its not a slip screen at all. Inside runs, Counter Runs, Misdirections Runs, Draws, and Trap runs will kill this.
As far as wide receiver screens, you HAVE to shift AND slant your d line to the Wide out side.....and then D contain your defensive end. Try it on the practice field....plays over. You also have to have man to man coverage in most cases...with a BnR.
Slip screens can be stopped with ease, you just have to know when there coming, and know when to stop them.
Once your opponent trys this twice, and he looses yards both times with this tactic...lol, you wont see it very much.
This tactic canalso be used for outside runs, with additional wrinkles into it, but....I'll leave it at that.
