HB Blast is a downhill power run out of the I Form Tight set with 22 personnel, showing a fullback lined up directly behind the quarterback and the halfback stacked behind him. The blocking scheme sends the fullback through the hole first to seal off the lead defender (the Iso block) while the offensive line blocks straight ahead, and the halfback follows tight behind him through the A or B gap for a downhill, north-south run. This is a pure run play, not a play-action or RPO look, and the primary read is the fullback's block, hitting the hole the instant the FB clears the gap rather than bouncing outside.
Pre-snap, identify the middle linebacker's depth and alignment, if he is stacked tight behind the nose it signals a strong run fit designed to plug the interior gaps. Watch for a Sam or Will linebacker crashing down early, which tells you the defense is selling out to stop the fullback's Iso block. Look at safety depth, a single high safety often means the box is loaded and this play will get contested at the line. Defenses that run heavy man coverage with blitzing linebackers can be vulnerable to this play since it does not rely on receiver separation. Post-snap, key on whether the user-controlled defender flows downhill immediately or sits, since a user spy or lurking linebacker can blow up the play before the fullback finishes his block.
Use HB Blast on short yardage and goal line situations where you need a tough, physical gain of one to three yards behind lead blocking. Check the box count pre-snap, this play thrives against light boxes or when the defense shows a two high safety shell with only five or six in the box. If the defense stacks the line with eight or nine in the box, consider audibling to a play-action pass like PA Ctr Shot or PA Boot to punish an overloaded run fit. Trust the fullback's Iso block and stay patient, do not juke laterally before the hole opens, mash through the initial gap. Pair HB Blast with HB Power O and HB Counter in the same drive to keep linebackers guessing between quick downhill hits and misdirection runs.
