Just like the Arkansas Razorbacks formation, wildcat, this play is confusing to all defenses that never faced it.

Double Reverse start out with a motion by RB.
As soon as the RB is three steps away from the QB, the ball is snapped. QB hands the ball to RB, RB hands to slot WR, finally hands it off to the QB.

The following attribute for position:

QB= Vince Young type. A quarterback in this play and/or formation can hurt a defense very badly.
