HB Duo

Read the frontside defensive tackle alignment pre-snap since Duo wants a base front rather than an overloaded bear or 46 look that stacks extra bodies inside Watch linebacker depth at the snap, if they are sitting shallow and downhill they can beat the double team block before it climbs and blow up the play in the backfield User controlled defenders flying downhill immediately after the snap are the biggest threat, spy or blitz the interior gap to shut this down before the back can press the hole Check safety rotation, if both safeties are deep in a two high shell the box is lighter and Duo has room to work, but a single high shell often means an extra run defender is cheating up Zone dropping linebackers who stay patient and read the mesh point can string the play out to the sideline, so look for aggressive fits versus passive ones to know if the cutback lane will open
