Corner Double In is a man beating concept out of Singleback Trips Close that puts two corner routes from the trips side to attack the deep outside quarters while a pair of dig or in breaking routes settle underneath to punish off man and zone drops. The single receiver or tight end backside typically runs an in or dig as a hot route alternative if you need a quick answer against pressure. Primary read progression starts with the outside corner route against the CB leverage, then works to the underneath in routes if the corner is capped by a safety, and finishes with the backside breaking route as the checkdown against a hard blitz.
Read the cornerback press or off alignment pre snap since press man with no safety help is the ideal shell for the corner route to win outside Watch the free safety depth and rotation after the snap because a rotation to the trips side signals a possible cloud or quarters look that will squeeze the corner route Key the underneath linebackers and their zone drop depth since shallow drops open passing lanes for the in routes but deep drops can jump those routes for a user pick Identify Cover 3 buzz or Cover 4 quarters shells that stack the deep outside third or quarter, as these coverages force you to peel off the corner route and live underneath Look for blitz tells like a walked up slot corner or overloaded trips side, which should push you to your hot route or backside checkdown instead of the full progression
Check the safety alignment pre snap because a two high shell tells you the corner routes have help over the top and you should prioritize the underneath in routes instead
Motion the slot receiver to identify man versus zone before the snap since a defender following the motion confirms man coverage and opens up the corner route as a legit outside shot
Use this play on second and long or third and medium situations where the underneath ins can move the sticks even if the corner routes get taken away
Hot route the backside receiver or tight end into a quick out or slant if you are facing a known blitz team to give yourself a fast answer versus five or six man pressure
Pair this play with Slants or Stick from the same set to keep the defense guessing between quick game and the deeper corner shots, forcing linebackers to respect both levels
