I am not too sure of where i found out about this play (i'm pretty sure it was from someone off here) but this play is fire! if you wanna conver on a 3rd and long this is my "money play". It's out of the shotgun tight formation. found in ARI (probably others i just ARI) and you're gunna streak your x receiver, motion him to the left, and sent your LB receiver on a slant to the left. And depending on how you're feeling, slant your B receiver on a slant left, or a curl route. Anyway, if the d is playing a cover 2, X is ALWAYS open, and if they press coverage then LB will be open, and then if they play cover 3, wait for your B guy to slant over or your A guy to run his corner route. and if all else fails you got your RB out of the flats. This play has bailed me out on so many long situations. or even 2nd and 7's. Enjoy it!
