It's a lazy playcall for many of these new OC's who don't have an identity. Typically, those guys have 'play offenses' meaning they see a play work well in someone else's offense and then decide to incorporate it, even if it's not particularly useful in their scheme. In general, its not an effective playcall. We would use it as a sub for a check with me. For example, if the corner was laying 5-7 yards off and you had numbers then the QB would just flip it out there while everyone else executed whatever play was called. It was never a called play though. But after a while we stopped doing even that because corners would sag off to bait us into that throw and just blow it up whenever it was thrown. It's gotten way overused by OC's who don't understand what the role the play is supposed to serve. It's a constraint play and nothing more.
