45 Quick Base is a designed HB dive run out of Shotgun Trips Slots Close with 10 personnel. The diagram shows three vertical routes stretching the defense on the trips side while the backfield features a short crossing action near the line, with the dive path marked by the red arrow hitting between the guard and center. The interior line blocks straight ahead to create a downhill lane, and the primary read is the initial gap: hit it hard on the dive unless the box is stacked, at which point the design leans on numbers advantage from the vertical routes drawing defenders away from the box.
Pre-snap, count the box defenders and check safety depth since a light box with safeties at 10-plus yards signals a green light for the dive. Watch for run blitz indicators like linebackers creeping to the line or a safety cheating down into the box, which kills this play immediately. Post-snap, user-controlled defenders flowing hard downhill or a spy sitting in the A-gap will blow up the dive before it develops. Man coverage on the trips side with no underneath help suggests defenders are locked on receivers, which usually means light box run support and a favorable dive lane. Zone shells with linebackers sitting deep in their drops can still leave the interior gaps clean, so read linebacker eye discipline at the snap to confirm the lane is there.
Check the box count before the snap since this is a true dive and needs six or fewer defenders in the box to hit efficiently.
Use the trips side vertical routes as window dressing to bait linebackers and safeties into abandoning run support responsibilities.
Pair this with 60 Go or Streak from the same set so defenses respect the deep shots and start playing softer fronts against the run.
Run this on early downs, first and second and short yardage situations, to keep defenses honest and set up RPO or PA Read looks later in the drive.
Avoid calling this into known run blitz fronts with stacked linebackers since the dive has no lead blocker to handle extra rushers.
