From @Brandon Patterson :

Today we’re looking at the Hokies’ longer-developing routes; if using Tech’s terminology, Drop-Back passes are the main item, with Play-Action and Double-Move often built in. Because they take longer to develop than most plays, these can be hard to identify when watching from home or even in the stadium. For old under-center rules, many of these calls would be five- or seven-step drops, though from the gun they’re usually two or three. Because the QB is holding the ball longer, many of the routes run off the TV screen or out of your peripheral vision, and you only see their results after the ball is thrown.
