45 Quick Base is a run play out of Shotgun Trips with 10 personnel that hands the ball off on a dive up the middle. The offensive line fires out for a standard zone/gap dive blocking scheme, with the fullback or lead blocker (in this case the diagram shows a lone blocker crossing to the point of attack) sealing the interior gap for the running back. With no route concept drawn beyond the backfield action, this is a straight downhill run designed to attack light boxes, and the primary read is simply which gap the line opens up for the back to hit.
Pre-snap, identify the linebacker depth. If both backers are sitting shallow and tight to the line, this play has a low ceiling since the dive lane will be crowded immediately. Look at the safety alignment. Two deep safeties usually means a lighter box, which favors this interior run. Post-snap, key on any blitzing linebacker shooting the gap the dive is designed to hit, since a well-timed A-gap blitz can blow this play up before the back gets to the line. This play struggles against heavy fronts like a 4-3 under or bear front with extra defensive linemen crashing inside. It performs best against defenses playing base zone coverage that keep linebackers reading run-pass rather than teams stacking the box on early downs.
Use this out of Trips when the defense shows a light box or has rotated extra defenders to the trips side, leaving fewer bodies inside to defend the dive.
Check the defensive front pre-snap. If both linebackers are stacked tight over the center, consider audibling to a different run direction or motioning a receiver to shift the box count.
Run this on early downs (1st and 2nd) to stay ahead of the sticks and keep the defense honest against your pass-heavy Trips concepts like Four Verticals or Levels.
Pair this play with RPO Base Alert Bubble or RPO Alert Screen from the same set so the defense has to respect both the dive and the quick perimeter throw off similar formation looks.
Use manual ball carrier control to press the hole and let the blocking develop before committing to a lane, since this is a gap scheme dive rather than an outside zone stretch.
