Normal is the base alignment inside the 46, and it is a defensive formation, not an offensive one, so the "personnel package" here is a heavy front seven with only two true deep-capable defenders behind it. Four down linemen sit head up on the offensive line with two linebackers stacked inside and a third defender walked down into the box, leaving two corners on the outside and a single safety with true range. Compared to other 46 sets that shift bodies wider or drop an extra hybrid defender out to the slot, Normal keeps everything condensed between the tackles, which is exactly why it wins the line of scrimmage against inside zone, power, and split flow runs.
Use Normal on first and second down when the offense shows two backs, a tight end, or any heavy personnel, and get out of it the moment you see three or more receivers to a side.
Pair Cover 1 Hole with a user controlled hole defender and read the quarterback's eyes: sit at 8 to 10 yards, then break on the shallow cross or drag once the receiver clears the linebackers.
Run Inside Blitz on second and short or third and one to eliminate the quarterback sneak and the interior run, then show the exact same alignment and play Cover 3 Match on the next snap.
Save Engage Eight for goal line and short yardage only, and manually drop one rusher into the middle if you suspect a play action shot.
Use Cover 2 Invert as your changeup after two or three one high looks, since the late rotation baits corner routes and deep outs that the offense read as open pre-snap.
