HB Slash Fk End Arnd is an end around trick run out of Singleback Wing 12 personnel, showing a fake handoff to the HB before the ball goes wide on the end around action. The diagram shows the primary ball carrier motioning across the formation and taking the handoff to attack the edge, while the offensive line and wing TE set up blocks to seal the perimeter and open a lane outside the tackle box. This is a gap exploiting misdirection run designed to punish overaggressive run fits and flow to the fake, not a pass concept, so the primary read is simply hitting the edge lane as it develops off the end around action.
Key the backside defensive end and outside linebacker, if they crash hard on the initial fake without staying home on the edge, this play will hit big. Watch for a scraping middle linebacker, if he stays disciplined and reads the end around action instead of biting on the fake, he can close the lane before it develops. Check corner alignment on the play side, an aggressive corner who squeezes down in run support can blow this play up before the ball carrier turns the corner. If the defense shows man coverage and mirrors the motion with a defender, that is a sign the end around is spotted and the play should be checked at the line. Spy or contain defenders on the edge are the biggest threat, a disciplined edge defender who stays square and does not chase the fake will string this run out for a loss.
Call this on early downs when the defense has shown aggressive run fits or heavy edge pressure on previous snaps so the fake sells harder.
Watch pre-snap for the defensive ends and outside linebackers crashing hard inside, since that flow creates the cutback and edge lane this play needs.
Motion recognition matters here, if the defense shows man coverage and follows the motion man across the formation, expect a numbers disadvantage on the edge, so consider bailing to a different play.
Pair this with HB Power O and Counter U in the same play calling sequence so defenders start keying inside runs, then hit them with this end around to expose their downhill pursuit.
Use in short yardage or first down situations against defenses that have been stacking the box, since this play thrives when linebackers are already flowing toward the fake before the edge ball carrier gets outside.
