HB Dive out of Singleback Tight Y Off Flex is a straight downhill run play that sends the HB directly through the A gap behind the center. The offensive line executes a base blocking scheme up front, with the fullback duties absorbed into the interior line push since there is no true lead blocker in this personnel grouping. This is a pure run play designed to test a defense's interior gap discipline rather than a man or zone beater in the passing game, and the primary read is a one cut decision for the HB to hit the initial crease between the guards or bounce off a bubble if the middle linebacker over-commits.
Watch for a stacked box pre-snap with the middle linebacker sitting tight behind the defensive line, which signals the defense is selling out to stop this exact concept. If the defense shows a 46 front or heavy run blitz package with both linebackers crashing downhill at the snap, this play will get blown up before the HB reaches the line of scrimmage. Cover 2 or Cover 3 shells with light boxes and safeties staying deep are the most vulnerable to this dive since there are fewer bodies to fill gaps quickly. Post-snap, key the defensive tackles' first step. If they are shooting gaps aggressively rather than reading the play, user your HB to cut away from the initial penetration. User a linebacker to spy the A gap if you are on defense against this tendency, since offenses that lean on HB Dive often become predictable in short yardage counts.
Use this play in short yardage and goal line situations where you need a quick, decisive gain without exposing yourself to a broken tackle in the open field.
Check the defensive front pre-snap for a bunched box with four or more defenders inside the tackles, since that alignment can clog the dive lane and force a quick alternate decision.
Pair this play with Jet Sweep or Jet HB Power from the same set to keep defenders honest on outside width, making the interior dive hit harder once the defense starts flowing wide.
Snap the ball quickly against defenses that show blitz looks with linebackers creeping to the line, since the dive hits before extra rushers can fill the gap.
Avoid calling this on third and long since the low ceiling of this run makes it a low value play when you need explosive yardage.
