The "Hand Sweep" is nothing more than the old Wing-T “bucksweep”.
For the Hand Sweep, motion is optional, but used to hold the backside defender with fake reverse action.
The H-back blocks the same as power option, and looks to log the DE. With Hand Sweep, the H-back is more man-conscious, looking to kickout the DE if he takes an outside-upfield path. The H-back can be replaced by a tight end with no change (reach block) in assignment.
Split End – who is the bigger, physical wide receiver (Y) cracks first backer in the box.
Playside Tackle maintains his power B-gap track
Backside Tackle will hinge, like he does in power and counter.
Center blocks back, like he does in power and counter.
Playside Guard – will pull to block the support defender. If the defense is in man coverage (the Y receiver’s defender chases him inside), the guard will look to log the first backer to clear. If the defense is in zone (the support player just sitting in the flat), the guard will kick the defender outside.
Backside Guard - the backside guard will skip pull to pick up the backside linebacker scraping over the top. If this backer tries to run-through the open playside A-gap, the guard will pick him up. If the backside backer shoots the backside B gap, the guard will not pull and just pickup the linebacker.
One of the better methods of defending Wing-T is by matching numbers with a reduction (Under) front, making it difficult to get enough blockers at point of attack. To accommodate for this front, as the playside tackle would have a terrible angle to account for an A-gap defender, the playside guard will make an “IN” call. This communicates that he is staying “in” (not pulling) and adhering to his A-gap track. This now reverts back to how power is blocked, with the exception that the backside guard will now be pulling for playside defensive support player.
