From my understanding nobody in the history of football has ever run a double reverse. What most commentators call the "double reverse" is really a single reverse, wrap around, or whatever you want. Here is why: A double reverse has 3 hand offs. First,QB hands ball to RB1 who runs left. Then, RB1 hands off to RB2 who runs right that's the first reverse(but is commonly called the "doubel reverse"). For a real double reverse, RB2 hands off the ball to RB3 (or WR1 or whomever)who runs to the left. As far as I know this has never happened in the NFL. So, please commentators get the right term down.
