The 3-5-3 stack defense is a very deceptive defense. This defense has the linebackers stacked behind the defensive linemen. This will allow the defense to disguise who will blitz or stunt. This features 3 defensive linemen, 5 linebackers and 3 secondary players. This youth football defense is not very common in youth football, at least not in my league. Because this defense is uncommon, it could illustrate a problem for offenses that have not seen it before.
“Indy” is a blitz play where we have the defensive linemen slant inside and the linebackers blitz outside. In this case we have the defensive linemen slant down and the linebackers blitz outside. This creates a problem with the offenses blocking scheme. It will confuse the offensive linemen because they will have a defender shooting their inside gap and a defender shooting their outside gap. There is an old saying you live by the blitz and die by the blitz- so blitz strategically.
