Dime 2-3-6 is a defensive set, not an offensive one, and that distinction matters because every play in the list is a coverage or pressure call. The personnel is Big Dime 4-1-6: four defensive linemen tagged RLE, RRE, RDT and NT, a single subbed linebacker (SUBLB), and six defensive backs including a slot corner (SLCB) aligned over the No. 2 receiver. That gives you a four-man front with enough interior beef (NT plus RDT) to hold up against single-back runs while still fielding six coverage defenders, which is the whole appeal compared to standard Dime 1-4-6 or Dime 3-2-6 looks that trade line weight for extra second-level speed.
Where this set separates from the rest of the Dime family is the balance between rush and coverage. With four down linemen you generate natural pressure without dialing up a blitz, so calls like Cover 3 Match, Cover 4 Palms, Press Quarters and Tampa 2 let you drop seven and still get home. The lone SUBLB is usually a coverage linebacker or safety hybrid, which means offenses cannot reliably attack the middle hook with a tight end or back the way they can against true 4-1-6 with a thumper in the middle. Pressure packages (Edge Blitz 0, Dbl Safety Blitz, Over Storm Brave, Overload 3 Press, Sim Pressure 3) all work off that same four-man shell, so your blitz and your base look identical pre-snap.
The matchup advantage comes from the SLCB and the two extra safeties. Bracket calls (Double Bracket, Double Bracket Switch, Bracket 9 Switch, Bracket Switch Willie) let you double the opponent's primary slot threat while leaving man or quarters coverage on the boundary, which is how you erase a single dominant receiver in a competitive matchup. Against spread offenses in 10 or 11 personnel, this set answers empty and four-wide sets without conceding the run game entirely.
Live in this set on third and long, two-minute drill and any snap where the offense shows 10 or 11 personnel in a spread alignment
User-control the SUBLB or a safety and sit in the middle hook, because that is the area every coverage in this set concedes by design
Rotate between Cover 3 Match, Cover 4 Palms and Press Quarters when defending two-high beaters, and mix in Roll King or Roll Ring to disguise the rotation post-snap
Save Bracket 9 Switch and Double Bracket Switch for the opponent's best receiver on third down, then manually shade your other corner inside to kill slants
Use press hot routes on the boundary corners against quick-game offenses, and back off with off-man audibles if you are getting beaten on fades and comebacks
Do not stay in this set on short yardage or second and short, audible out to a heavier Nickel or base look before the offense motions into a run formation
