HB Blast is a downhill Iso run out of the I Form Slot 21 personnel set, showing the FB leading through the hole with the HB following directly behind him for a power isolation run at the point of attack. The diagram shows the offensive line covering their gaps with the FB assigned to iso block the first inside linebacker that shows in the hole, clearing a lane for the HB to hit between the guard and center. This is a straightforward gap scheme run play with no route combos or pass options, and the primary read progression for the HB is to press the FB's block, read the Mike backer's fill, and cut off the FB's shoulder into the vacated crease.
Check the Mike linebacker's depth pre-snap: a linebacker sitting tight at five yards or closer signals he is ready to fill the iso lane fast, so be ready to bounce the run if he wins the block. Watch for a safety creeping down into the box pre-snap, which indicates an eight man front designed to stop this exact iso concept. Post-snap, key the FB's block target: if the user controls the Mike and jumps outside the FB's block, the HB should cut back inside behind the guard. This play struggles against gap sound 4-3 fronts with a heavy Mike blitz called, since the extra defender fills the iso lane before the FB can climb to him. It beats light boxes and nickel or dime sub packages where the defense has removed a linebacker for pass coverage, giving the FB a clean angle on a smaller defender.
Use HB Blast on early downs against base fronts to establish a run identity and set up your play action shots later in the drive.
Watch pre-snap for the Mike linebacker's alignment: if he is stacked directly behind the center, user the FB into him immediately after the snap to win the iso block.
Against odd fronts or bear fronts with extra defenders in the box, kill this play at the line and check to HB Stretch or Jet Sweep to get to the perimeter instead.
Pair HB Blast with PA Power O and PA Ctr Waggle since both plays sell the same downhill FB action before breaking outside, keeping linebackers frozen on run fits.
Run this on short yardage and goal line situations where you need a quick, decisive north south push and defenders are likely to key run anyway.
